Congratulations on the start of the 7th obstetric week! There is a second month of pregnancy. Technically, the unborn child is still considered an embryo, he even has a small tail, which, however, will disappear in a few weeks.
What happens at this time? On the tiny hillocks, which will soon become hands and feet, appeared the rudiments of future palms and feet.
Fetal skin at week 7 is still transparent, so all internal organs and thin blood vessels through which blood moves can be seen through it. Future eyes are already half closed for centuries, the formation of eye lenses is underway. Both hemispheres are actively developing. brain. and in the liver of the unborn child red blood cells are formed. At this time, the fetus already has a pancreas and even an appendix.
Fetus sizes at week 7 comparable to the size of blueberries: its length is about 13 mm, and it weighs almost half a gram.
Will ultrasound show 7 week of pregnancy
With the emergence of suspicions of an interesting situation, many people remember about ultrasound. Whether ultrasound is harmful at 7 weeks of pregnancy, the fear that such thoughts usually accompany. In fact, there is no direct evidence that such a study has a negative effect on the embryo. However, as well as there are no inverse proved opinions. Therefore, if ultrasound is dangerous at 7 weeks of pregnancy, no one will tell you for sure. As a rule, the patient has good reasons for referring to such manipulation, and the information content of the method covers the probable harm.
Such an examination makes sense if you are worried about the following symptoms:
- Nagging pains
- Suspicion of Ectopic Pregnancy.
The ultrasound will dispel or confirm suspicions, but that you get an accurate picture of what is happening to you, do not even hesitate.
The hgc index at 7 weeks gestation: the norm and deviations
The hCG indicator in the 7th week of pregnancy: normal and abnormalitiesIn the 7th week of pregnancy, important organs are formed in the fetus. The nervous system and the brain develop. During this period it is very important that the child develops correctly, without deviations. Otherwise, it threatens serious pathologies. To determine how the development of the child occurs, a pregnant woman should pass a blood test for hCG at week 7. This is a very important method of examination, which gives you a clear picture of the state of health of the mother and fetus.
Fluorography at the 7th week of pregnancy
The question of whether it is possible to undergo fluorography at this time is another one that worries the future mother. Usually it is already set after the fact, since most of us are in the seventh week after conception and do not know that we are pregnant. Most experts are inclined to believe that radiation received from a photofluorograph can be potentially dangerous to the fetus in the early stages, so if you are scheduled to undergo fluorography, it is only in an emergency, if you suspect tuberculosis, for example. And if you can wait, the procedure is better to postpone after 20 weeks. But on the other hand, modern photofluorographs are more secure than models that were operated 10 years ago, so there is hope that such an X-ray test will not be anything bad for an embryo.
What is the level of normal progesterone 7 week of pregnancy
Progesterone, also called a pregnancy hormone, is responsible for maintaining and maintaining this condition in the expectant mother. As the pregnancy progresses, its blood level increases. Research on the measurement of this hormone are carried out on an empty stomach, eliminating physical exertion. By the time of 7-8 weeks after conception, the rate of progesterone is 32.98 +/- 3.56 nmol / l. If the level of the hormone is lowered or, on the contrary, it is elevated, it speaks of any pathological conditions, the doctor draws conclusions by conducting another diagnosis.
What happens at week 7 and the significance of hCG?
HCG in the 7th week of pregnancy can tell a lot. Of course, he will not show exact deviations, but he will tell about the general condition. For example, if there is an abnormal development of the brain, the level of hCG during pregnancy will be low. This suggests that the fetus is lagging behind in development. And the lower the score, the stronger the deviations.
For a period of 7 weeks, important organs such as the kidneys, liver, and digestive tract are formed in the fetus. All this requires careful monitoring in order to identify pathologies in time and eliminate them whenever possible.
When does HCG necessarily take place?
There are a number of indications for which it is important to observe the increase in hCG during pregnancy. He makes it clear about the state of the mother. These indications are:
the threat of miscarriage, suspected ectopic pregnancy, amenorrhea, possible tumors.
In these cases, the woman is regularly sent to determine the level of hCG during pregnancy.
Norm hCG at week 7
At the 7th week of pregnancy, hCG should be between 50,000 and 200,000. This indicator indicates a normal course of pregnancy and no abnormalities. Although small errors are still allowed. If the deviation is from 30,000 and more, then the woman is sent to the surrender of the re-analysis.
Before passing the analysis, the woman must specify the duration of the pregnancy. The indicator depends on it. Even the two-week difference shows significant changes, because the level of hCG during pregnancy increases twice every two days.
Deviations from the norm
Elevated hCG during pregnancy at 7 weeks can say the following:
on multiple pregnancies, on the development of Down syndrome in a child, on diabetes in a woman, on severe toxicosis, on serious pathologies in the fetus.
Low levels of hCG during pregnancy can mean:
missed abortion, ectopic pregnancy, placental insufficiency, delayed development of the child, the threat of miscarriage.
Only a woman should not panic ahead of time. Repeated analysis may show the rate of hCG during pregnancy.
If a bad result of hCG is necessary, it is necessary to pass a repeated analysis of hCG and make an ultrasound. But in any case, pregnancy with low hCG can be saved.
How to pass the analysis? To see the growth of hCG during pregnancy, a woman takes blood from a vein. By the way, you can see the level of this hormone in the urine, but there its content is two times less than in the blood. And tests for the determination of pregnancy are made by a similar method. They determine the level of hCG, and then give the result of completed fertilization. To determine the exact result at the first stage of pregnancy, it is recommended to take the analysis not earlier than three days after the delay of menstruation.
If you do it earlier, the result may show the absence of pregnancy. Blood is taken from a woman on an empty stomach, or after 6 hours after the last meal. It is desirable that revealed hCG during pregnancy rate, adhere to the first option. So the result will be more accurate. On the eve, and it is better a few days before the analysis should not engage in physical activity. If a woman is taking medication, then she must inform the doctor. Some drugs cause normal growth of hCG during pregnancy.
It is important for the future mother to remember that if the doctor sends her to repeat the analysis of hCG, then it is necessary. This does not mean that her child does not develop correctly. Because many women immediately panic, depression, which is very harmful to the child. Sometimes, to determine the norm of hCG during pregnancy, you will need to re-pass two tests. And it's not scary.
You need to be afraid that, due to excessive experiences, an actively developing baby will be harmed during the 7th week of pregnancy. Until the doctor makes an accurate diagnosis, the woman does not need to worry. And if low or high levels of hCG are detected during pregnancy, then there is still a lot of way to determine the accuracy of this analysis. Testing is a very important procedure during pregnancy. Based on their results, one can judge the state of the mother and the baby. HCG is one of the mandatory tests that is assigned to each expectant mother.
- Chromosomal pathologies and fetal malformations
- Trophoblastic tumors
- Acceptance of human chorionic gonadotropin for therapeutic purposes.
HCG as a marker of fetal abnormalities
To control the development of the baby, each pregnant woman should undergo prenatal screening (see first trimester screening). It consists of several stages, including the evaluation of ultrasound data and the level of hormones, including hCG.
In the first trimester, at 10-14 week, examine 2 biochemical markers:
- PAPP-A (pregnancy-associated plasma protein A)
In the second trimester, at 16-18 week, a woman takes a triple test:
The data from these screenings, together with the results of ultrasound, allow us to assess the risks of having a baby with certain chromosomal abnormalities and developmental defects. The calculation of these risks is carried out taking into account the age of the mother, her weight and the health of children from previous pregnancies.
In the 90s of the 20th century, scientists noted that in the blood of mothers who bear children with Down syndrome, the level of hCG was increased two or more times. The mechanism of increasing the hormone is still not exactly clear, but it is the chorionic gonadotropin that is the most sensitive marker for trisomy 21 chromosomes.
Abnormalities of the fetus, leading to changes in the level of hCG:
- Down syndrome (high hCG and low levels of other markers)
- Edwards syndrome and Patau syndrome (low levels of hCG and other markers)
- Turner syndrome (unchanged hCG with a decrease in other markers)
- Severe neural tube and heart defects
In case of detection of an increased risk of anomalies, a woman can undergo additional examinations. To confirm the developmental disorders of the fetus with high accuracy helps invasive diagnosis. Depending on the gestational age, different methods are used:
- chorion biopsy
It is important to remember that if screening results are unsatisfactory, including the level of hCG, a consultation with a geneticist is required.
There are situations when screening is extremely difficult, and sometimes impossible. This happens when a multiple pregnancy. In this case, the level of hCG will be increased in proportion to the number of fruits, but it will be problematic to calculate individual risks for each baby.
HCG for ectopic pregnancy
Ectopic pregnancy is a condition in which a fertilized egg is attached anywhere, except for the inner layer of the uterus (endometrium). Most often it is located in the fallopian tubes, less often - in the uterus, ovaries, and even on the intestines. The danger of ectopic pregnancy is that it necessarily terminates (except for a few cases). As a result, a woman can die from heavy internal bleeding, which is very difficult to stop. But there is a “gold standard” of diagnostics that allows you to make such a diagnosis and take action in time. This ultrasound is combined with the determination of hCG in a woman’s blood.
When ectopic pregnancy conditions for the attachment of the egg is extremely difficult, so the trophoblast releases much less human chorionic gonadotropin than in normal pregnancy. If the level of the hormone grows extremely slowly, does not meet the standards for weeks of pregnancy, then it is necessary to conduct an ultrasound scan with a vaginal sensor in order to find the fertilized egg in the uterus or outside it. It is possible with a high probability at the level of hCG from 1000 IU / l. If the embryo is not found with this amount of hormone, then laparoscopic surgery and search for the ovum will be necessary.
Signs of ectopic pregnancy
- abdominal pain after delayed menstruation
- soreness during vaginal examination and intercourse
- sometimes - bloody discharge from the vagina
- fainting during menstruation
When the above symptoms appear, it is necessary to consult a doctor, make an ultrasound scan and pass the analysis of hCG (often in dynamics) to exclude an ectopic pregnancy.
Fading pregnancy and antenatal fetal death
Sometimes it happens that after a delay of menstruation and a positive pregnancy test, the signs of pregnancy do not occur or end abruptly. In these cases, the embryo dies, but for some reason the miscarriage does not occur. As a result, the level of human chorionic hormone, which corresponded to the gestational age, ceases to grow and then decreases. On ultrasound, you can see an embryo without a heartbeat or even an empty ovum (anembryonia). This condition is called frozen (non-developing) pregnancy.
Causes of missed abortion
- chromosomal abnormalities (most non-developing pregnancies for up to 10 weeks)
- maternal infections (often chronic endometritis)
- anatomical defects of the uterus
- maternal coagulation disorder (thrombophilia)
If a miscarriage does not occur after a detected missed pregnancy in the near future, it is necessary to perform a medical abortion or curettage of the uterus. If pregnancy fading is repeated 2 or more times, the couple should be examined to determine the causes of this condition.
If the fetus dies at a later date, it is called antenatal death. Since at long periods the level of hCG is not measured by weeks of pregnancy, it does not have a diagnostic value, although a decrease in the hormone occurs in any case.
Full and partial bubble skid
With the development of a normal pregnancy, the sperm cell, merging with the egg cell, forms a zygote in which the maternal and paternal genetic information is equally combined. But sometimes there is a loss of "female contribution", when the chromosomes of the egg as it were expelled from the ovum. In this case, a condition similar to pregnancy develops, but only on the basis of the paternal genetic material. This phenomenon is called a complete bubble skid. When a partial blistering of the information of the egg remains, but the information from the sperm doubles.
Both in normal pregnancy and in the case of blistering, the paternal chromosomes are responsible for the trophoblast and the formation of the placenta. In the case of doubling of these chromosomes, the trophoblast begins to develop at an enormous speed, releasing hormones, including hCG, in large quantities in the blood. This is the basis for the diagnosis of this disease.
With a blistering development of a normal pregnancy is impossible, it ends with a spontaneous abortion. But the biggest trouble is that the hyperactive trophoblast begins to invade the uterus, then beyond, sometimes turning into a malignant tumor with metastasis. Therefore, it is important to detect this disease in time and begin treatment.
Signs of blistering:
- uterine bleeding in early pregnancy
- unrestrained vomiting (more painful than during normal pregnancy)
- the size of the uterus is larger than it happens on such a period
- sometimes symptoms of preeclampsia
- rarely - rapid heartbeat, trembling fingers, weight loss
With such signs, consultation with a doctor, an ultrasound scan and measurement of the level of hCG in the blood are necessary. In normal pregnancy, the level of this hormone rarely exceeds 500,000 IU / L, and there are approximate norms for each gestational age. When blistering the amount of HCG exceeds them several times.
Treatment for a skidding is to remove the entire trophoblast from the uterus. This can be done by scraping or other surgery. Sometimes a relatively benign cystic skid turns into a frankly malignant chorionic carcinoma. This tumor metastasizes very quickly, although it responds well to chemotherapy.
Indications for chemotherapy for blistering:
- the amount of hCG exceeds 20,000 IU / l one month after the removal of the skidding
- increase in hCG level after removing the skidding
- metastases to the liver, stomach, brain
Chorionic carcinoma can occur not only after a blistering, but also after a safe delivery or abortion. In this case, 40 days after the end of the pregnancy, the level of hCG does not fall, but often rises. A woman may be worried about uterine bleeding and signs of metastases to the organs. In such cases, the treatment is carried out with the help of chemotherapy (methotrexate and other drugs), surgery and further observation.
Administration of human chorionic gonadotropin
The results of blood tests for hCG, including screening, may be affected by the intake of this hormone. It is usually prescribed for infertility and as a preparation stage for IVF.
Very rarely, it is taken in case of a threatened abortion at short notice. In any case, if you are taking this drug or any other hormonal drugs, be sure to notify your doctor.
When can there be a false positive result?
- As some sources indicate, the use of COCs (oral contraceptives) may affect the analysis. This is not correct information. Taking contraceptives has no effect on hCG levels. На результат анализа оказывает влияние прием препарата хорионического гонадотропина, обычно как этап протокола ЭКО.
- После родов или аборта ХГЧ обычно падает до нормы в течение 7 дней. Иногда ждут до 42 дней, прежде чем ставить диагноз. Если не упал, или начал даже расти, тогда это может быть трофобластическая опухоль.
- Другие опухоли могут давать повышение гормона при метастазах пузырного заноса или хорионкарциномы.
- There are other germline tumors, but they rarely give rise to hCG. Therefore, if there is a formation in the lungs, stomach or brain, plus high hCG, then the first thing to think about trophoblastic tumors with metastases.
Immunity against hCG
In rare cases, a woman’s body develops immunity against chorionic hormone. The formed antibodies to this substance do not give the fertilized egg to normally attach in the uterus and develop. Therefore, if 2 or more pregnancies of a woman have ended in an early spontaneous abortion, then it is necessary to pass an analysis for antibodies to hCG.
In case of positive results, treatment is prescribed during the first trimester. It consists of glucocorticoids and low molecular weight heparins. We must not forget that this pathology is very rare, so before treatment it is necessary to exclude other causes of infertility and miscarriage.
Determining the level of human chorionic hormone is an important step in monitoring the health of women and children. But this analysis should be prescribed by a doctor, since the norms of hCG for weeks of pregnancy have an average value, and incorrect interpretation of the indicator leads to unreasonable anxieties and disturbances, which is extremely undesirable during pregnancy.
Hello! Pregnancy test shows 2 strips, delayed menstruation for about 3 weeks. But on the ultrasound still have not found the ovum. Blood test for hCG: 7550 mIU / ml. How much more can you expect to visualize the embryo?
On modern devices, the ovum can be seen in the uterus or outside it already at a hormone concentration of more than 1000 mIU / ml. Therefore, in your situation, you should immediately consult a doctor to find a solution. You may have to undergo laparoscopic surgery. Delaying a visit to the doctor may result in internal bleeding after termination of an ectopic pregnancy.
At the screening at 13 weeks of gestation, risks were calculated, they were high for almost all pathologies. After the biopsy of the chorionic villi, the karyotype of the fetus 69xxx was obtained. Offer interruption. Is it possible in my case the bubble skid?
Triploidy may indicate the formation of a partial blistering. Since a fetus with such a set of chromosomes is not viable, you are advised to terminate a pregnancy with a subsequent ultrasound scan and control of the b-subunit of hCG. The material obtained after the interruption should be sent for histological examination.
After screening, I was given the results as hCG and PAPP-A values. The value of human chorionic gonadotropin slightly exceeds the norm. How dangerous is it?
The results of any screening should be given in the form of a quantitative value of individual risks. For example,
- Edwards Syndrome Risk: 1: 1400
- risk of Patau Syndrome: 1: 1600
- risk of neural tube defect 1: 1620
In this form, as the results gave you, it is impossible to determine the risks. Contact the laboratory, where they passed the tests, with a request to calculate individual risks.
Your baby is only 5 weeks old, and he has already achieved so much in development! The heart, which by this time has been divided into the right and left atrium, is already working. And on the 7th week of pregnancy, it will become a four-chamber and will begin to pump blood throughout the whole body. The vascular system also helps him in this: large blood vessels are now being formed.
The internal organs and systems do not stop their development: by this time the colon, appendix, intestine, which is now lengthened, has already been formed. The bile ducts appear in the liver, and the first insulin is produced in the pancreas. At the 7th week of pregnancy, lungs, bronchi, kidneys, and endocrine glands continue to form. The sex of the child is also determined, although on ultrasound, of course, this will not be seen yet: the sex glands will form into the testicles or ovaries, and a tubercle will form between the legs, from which the genitals will later stand out.
The fetus at 7 weeks of gestation weighs less than 1 g, its coccyx-parietal size is about 13 mm, the child himself gradually straightens. Almost half of the entire body is occupied by the head. It is not without reason that such a disproportionately large one is now - the brain is developing at an incredible speed. It is already divided into 2 hemispheres, and now 5 of its departments will begin to take shape, as in an adult.
The head and face of the embryo will continually improve. Now the outer and inner ear, the iris of the eyes, the pigment in the retina, the cilia of the eyelids are being formed. The eyes are set far enough away, but throughout pregnancy they will come together week after week, giving the face more and more human features. The rudiments of a nostril nose and upper lip are already visible. It is on week 7 that the milk teeth are laid and the jaws begin to take shape.
The nervous system does not stop its development - by this time it is already in principle formed and is only being improved.
Embryo pens develop faster than the legs: they can bend at the elbows and wrists, the palm is shaped, and even the rudiments of fingers are visible. The shoulders and forearms stand out, bone cells and the epidermis begin to develop. At 7 weeks of pregnancy, the fetus is already moving, but it is still so small that the mother, of course, can not feel it. The joy of the first sensations of his movements will come soon.
The umbilical cord is completing its formation: by the end of the 7th week of pregnancy, the uteroplacental blood flow will be fully established, and the placenta will become more dense, although its formation will end only by the 12th week. A mucus plug is now formed, which will block access to the uterus by harmful factors from outside and will protect and maintain this small intrauterine world in sterility.
Under the rapid growth and development of the fetus adapts the entire maternal organism. To the baby was comfortable to dwell in the womb, the uterus is constantly growing in size, trying to provide it with vital space. According to your tummy, it is not yet visible that you are in position, but the uterus at 7 weeks of pregnancy is already twice its size. Now it can be compared with a large orange.
Pain in the 7th week of pregnancy
Uterus supporting ligaments are constantly stretched, and some women feel this tension with pains on the sides of the abdomen. It's not scary. But if it hurts at the bottom, like during menstruation, cramping or sipping, and in addition the pain is felt in the back or lower back, then this may be a probable threat of interruption. Try not to perform any actions that bring the uterus to tone: do not wear high heels, avoid strong physical and emotional stress, do not take a hot bath, and generally eliminate any thermal procedures. If you notice bloody discharge, then immediately call a doctor or go to the hospital.
In addition to the back and abdomen, the 7th week of pregnancy can hurt the chest. A woman feels a tingling sensation or just a discomfort in her chest, which is slightly swollen.
Headaches are also frequent companions of pregnancy, including in the early stages. But now you have to look for safe methods of dealing with them: pills are now banned.
In general, the future mother, like any other woman, can get anything. If, along with pain, you see some warning signs in yourself, it’s better to be safe and consult a doctor about this once again.
If the abdominal pain is accompanied by bloody discharge from the vagina, you will have to go to the hospital for preservation. Do not tighten and do not wait until the bleeding begins at the 7th week of pregnancy. It can develop gradually, with a few bright red drops, but it can also begin at once abundantly. The risk of miscarriage this week remains quite high, but the chances of saving the child are always there, and also not low.
The main thing - do not disregard even the most insignificant, in your opinion, bleeding at the 7th week of pregnancy. Because in addition to the threat of interruption, there may be other serious causes of bloody discharge from the vagina. In particular, polyps and other tumors in the cervix and uterus can make themselves felt that way. In this case, the above pain is not observed. In the same way as with erosion of the cervix, when bleeding may increase after sexual contact.
Attention should also be paid to vaginal discharge. You should be alerted by bloody discharge (red, brown, or even beige), yellow-green and grayish discharge, thick, cheesy or frothy discharge, and any others that seem strange to you, unusual or suspicious. If at the same time you experience itching, burning, irritation and soreness in the genital area, as well as if the discharge emit a strong smell, then it is necessary for the gynecologist to appear immediately.
However, do not be afraid of ordinary leucorrhoea, which under the influence of hormones can become more liquid or slippery and abundant. Such discharge in the 7th week of pregnancy is quite normal and is one of its signs.
Signs and symptoms in the 7th week of pregnancy
You probably already experience some signs of pregnancy: nausea or dizziness, drowsiness or fatigue, changes in appetite or taste, mood swings or changes in the chest. Not only does it hurt and is sore, but it can also be covered by the venous mesh.
At the 7th week of pregnancy, these may be supplemented with new symptoms: frequent urination, emotional outbursts, unfounded fears, gastronomic distortions, excessive salivation, problems with the stool and digestion, discoloration of the labia majora. Perhaps your skin pigmentation will change: nipples or stripes on the abdomen will darken.
But on the whole, the signs and symptoms at the 7th week of pregnancy become almost irrelevant: you have not had monthly periods for 2 weeks, and even if you have had such long delays before, all the same, by that time it was time to do more than one test to determine of pregnancy.
7 week of pregnancy photo
A woman in the 7th week of pregnancy often feels like an old galosh, and not a fluttering butterfly. She is plagued by many symptoms that impede a new pregnant life: lack of air, bloating, heartburn, and constipation. A woman may experience increased anxiety and anxiety, and may experience insomnia.
It is difficult to say, lucky such women or not. After all, they have now moved to the new status, which many only dream of! Therefore, any inconvenience should be perceived with gratitude.
But, of course, with strong toxicosis, it seems as if nothing at all is much better to experience. And there are women who, at the 7th week of pregnancy, well, they don’t feel anything — everything, as usual, except in the sides, it seems, has become a bit wider (something pants are very tightly fastened on the stomach).
It seems to some women that they are about to get sick: my head hurts, my nose is stuffed up, and even the temperature has been holding for several days - 37.2 C. It turns out that this condition during pregnancy can also be the norm. If nothing else bothers you, then most likely it’s just rhinitis of pregnant women. A slight increase in temperature the body reacts to changes occurring in it.
When the temperature rises to high elevations, and along with nasal congestion, there is still a cough, sore throat or body aches, then it is time to heal. Check all your actions with the doctor. Remember that Aspirin is contraindicated during pregnancy. Drink plenty of warm tea (but not raspberry or viburnum), put wet compresses, in extreme cases, you can drink Panadol after consulting a doctor. And by all means lie - loads to you are contraindicated now. Be attentive to yourself: sometimes the temperature rises with the threat of abortion - watch for other signs.
Cold in the 7th week of pregnancy
In general, it is very undesirable to catch a cold: up to week 12, the laying-out, formation and development of the main organs and systems of the child, which can be affected by both severely illnesses and especially medicines, continues. Therefore, if such a nuisance has happened and you have caught a cold, you will refrain from taking medication for at least 8 weeks.
The common cold has its own pitfalls: a strong debilitating cough can cause the uterus to tone, the stuffy nose makes it difficult to supply oxygen to the baby, too high a temperature can have a negative effect on the fetus. Therefore, of course, you need to be treated, but be careful in choosing the means: coordinate everything with your doctor, even folk methods - many of them are prohibited during pregnancy.
Sex at 7 weeks is not contraindicated, but only if the uterus is not in good shape and there are no threats of abortion. Against the background of hormonal changes, many women note an increase in libido and begin to experience more pleasure from sex during this period than before, not only at the physiological, but also at the emotional level: the fact of waiting for a common child brings the spouses closer. Therefore, if nothing prevents this proximity - enjoy!
But the alcohol at 7 weeks of pregnancy should be eliminated completely. Remember that he does the most harm in the first trimester. Alcohol gets to the child from the mother through the bloodstream in a constant amount.
At week 7, the nervous system and the brain, as well as other organs and systems, are actively developing. And all these processes may be subject to alcohol influence. More than others, it is the nerve and brain cells that are damaged or completely destroyed, and the consequences of this impact can manifest themselves at any time, even when this embryo becomes once a teenager. Of particular risk is the development of fetal alcohol syndrome in the fetus - as a rule, in the case of alcohol abuse by the mother. In general, pediatricians urge to refrain from the use of any alcoholic beverages in any quantity for the entire period of pregnancy and until the very end of breastfeeding.
It is possible to check the condition of the embryo and evaluate its vital signs with the help of an ultrasound scan at the 7th week of pregnancy. If by this time you were not yet sure about your pregnancy, then an ultrasound scan will show her how many fruits and where they are fixed and how they develop: the baby's heartbeat, his physical activity. Today, ultrasound in the early stages is done mostly vaginally. Doctors claim that this is an absolutely harmless procedure, and there is a lot of benefit from it: it will make sure that the pregnancy develops in the uterus, and can even reveal an increased uterine tone and other disorders, if any: gallbladder, endometriosis, myoma and others. That is why gynecologists often insist on an ultrasound at the 7th week of pregnancy. And it is better to do this in a specialized clinic or office, where the uzist works with pregnant women.
Analyzes (hCG, progesterone) in the 7th week of pregnancy
So, the pregnancy was confirmed on the ultrasound, the time was set, everything is fine with the baby - it’s time to get registered at the 7th week of pregnancy. You will certainly be sent to a study that will include a number of analyzes:
- urine - common, according to Nechyporenko,
- of blood - common, sugar, biochemistry, clotting, blood type and Rh factor, HIV-AIDS,
- Kala - on egglist,
- vaginal smear - to identify genital infections.
You will also need to undergo an examination by a therapist, an ophthalmologist, and a dentist and make a cardiogram of the heart. The future father will not shirk his examination: he will have to donate blood from a vein for the Rh factor and undergo fluorography.
These are obligatory tests for all, which a woman must pass when registering, and in theory all of them should be carried out free of charge (but try to prove it to someone).
However, in some cases, you may be sent for additional tests - for example, a quantitative urine test for hCG or a blood test for other hormones, in particular progesterone. Do not worry, because doctors want to make sure that the pregnancy is developing normally and the fetus is fine. This can just tell the concentration in the human blood or urine of human chorionic gonadotropin (it stimulates the production of estrogen and progesterone), which increases to 10-12 weeks all the time, as well as the level of progesterone - this hormone relaxes the muscular muscles of the uterus, preventing miscarriage.
Calcium is important now. Not only, of course, but milk teeth are laid, so do not exclude it from your diet. However, a lot of calcium is also not good, because it tones the uterus, and at the 7th week of pregnancy it is unsafe.
You are very lucky if by the 7th week you do not suffer from toxemia and still do not experience other "charms" of pregnancy: bloating, heartburn, constipation. In this case, you can have everything you want, with an adjustment in the direction of healthy foods and dishes. Your diet should be plenty of fresh natural plant foods, fats, complex carbohydrates, animal protein. But come up with everything wisely: it's about fresh lettuce with leafy greens, not fried potatoes, and boiled meat, not grilled chicken. Do you want to harm? Побалуйте себя, но совсем чуть-чуть - научитесь договариваться со своим непредсказуемым организмом и предлагать ему альтернативные полезные продукты вместо гадостей. Постарайтесь ограничить употребление сладкого и соленого, откажитесь от копченостей и острой пищи.
Хуже и труднее, если вас мутит с самого утра и есть либо не хочется, либо не представляется возможным. Не страшно, если вы не можете впихнуть в себя ни кусочка нужного в этот период мяса - замените его другими белками. Ешьте то, что можете - будет больше пользы. But still try to make a choice in the direction of healthy products. “Snacking” from the very morning will help to nauseate nausea, without getting out of bed: nibble a cookie prepared in the evening or a toast - it will be easier. When toxicosis, be sure to try to eat at least something in the morning. And reckon with your intestines: so, with increased gas formation, you will have to give up cabbage and beans, even if you love them very much.
Blood test for hCG at the 7th week of pregnancy
HCG at 7 weeks gestation continues to grow. During this period, the level of hCG should double approximately every 3-4 days. If the hCG level is below normal for your period, or if the hCG stopped growing, this may be a sign of a missed abortion. On our site there is a separate article devoted to this topic: Zameshaya pregnancy: causes and symptoms. A frozen pregnancy at week 7 can be recognized by ultrasound.
What is hCG?
HCG - chorionic gonadotropin. This hormone belongs to the category of gonadotropic, i.e. It directly regulates the functioning of the reproductive system. It is synthesized by a fertilized egg, or rather its part, the trophoblast, from which the placenta will later be formed. Enhanced production of hCG begins at the moment when the villi of the chorion embryo in the process of implantation begin to grow into the endometrium of the uterus. Normally, hCG above 5 mMe / ml can only be observed in the female body and only if conception occurs. That is why it is also called the hormone of pregnancy. In the absence of conception, an increase in the level of this hormone may indicate the development of pathological processes, in particular, the formation of tumors in men and women.
Synthesis of other hormones
Due to the increase in hCG levels during pregnancy, the process of production of other important hormones is activated. The first is estrogen, it contributes to the proper development of the baby, supports a number of physiological changes in the woman’s body in the process of carrying the child, prepares her body for lactation. The second hormone is progesterone. It “works” primarily to create optimal conditions for the preservation and development of the fetus: prepares the uterus for proper implantation, balances the effect of estrogen, relaxes the ligaments and muscles, accumulates subcutaneous fat in a pregnant woman for the “stock” of necessary nutrients for the fetus.
What does the pregnancy hormone do?
Preservation of the corpus luteum
Yellow, or luteal body is called the temporary endocrine gland. It is formed after ovulation, when the mature egg leaves the follicle. If conception happened in the current cycle, then until about 4 months of pregnancy, the corpus luteum will participate in the development of the embryo and its nutrition. After all its functions will take over the placenta.
Impact on sexual differentiation in boys
Thanks to hCG, the male genitals develop in a male type. In addition, this hormone will stimulate the work of the genital glands and adrenal glands of the baby.
HCG regulates the development of pregnancy in the early stages
Why prescribe the analysis of hCG during pregnancy?
Blood on hCG during pregnancy is given first of all in order to accurately establish the fact of its occurrence. Unlike pharmacy tests, such analysis eliminates any errors due to non-compliance with instructions and incorrect interpretation of the result. Sometimes a woman is recommended to pass the analysis several times: the assessment of the growth of the level of hCG over time allows you to make sure that the pregnancy develops normally in the early stages. This parameter is especially important in those cases if the couple planned a child or went to a specialized clinic of assisted reproductive technologies.
By hCG, you can roughly determine the duration of pregnancy, as well as its feature, as the number of fruits. If a woman is waiting for twins or triplets, the concentration of human chorionic gonadotropin will be several times higher than usual.
Moreover, the hCG rate in early pregnancy is also taken into account when conducting the so-called double test as part of the first prenatal screening. The purpose of this study, which is always carried out in conjunction with a full-blown ultrasound scan, is to exclude severe abnormalities in the development of the fetus. Increased β-type chorionic gonadotropin in singleton pregnancy can be a symptom of Down syndrome, the presence of diabetes mellitus in an expectant mother, or the development of severe toxicosis requiring medical supervision. If, on the contrary, indicators are reduced, it is necessary to exclude Edwards syndrome, placental insufficiency and other factors that increase the risk of miscarriage.
Why do you need an analysis of hCG during pregnancy?
Beta-hCG: normal in pregnancy
In the structure of human chorionic gonadotropin, there are two subunits - alpha and beta. Alpha corresponds to similar subunits of pituitary hormones and is not considered for future mothers. When determining the indicators of hCG during pregnancy, the beta subunit is usually considered. It is recognized by the reagents used in pharmacy tests of all kinds, as well as markers that are used when performing laboratory tests.
Normal hCG levels during pregnancy begins to double immediately after implantation approximately every two days. Its growth, depending on the individual characteristics of the organism of the future mother, lasts for 8-10 obstetric weeks (that is, from the day of the last menstruation) and reaches “record” indicators at the end of the first trimester. After that, in the normal development of the fetus and the correct course of physiological processes, the concentration of chorionic gonadotropin decreases. By the 18th – 20th week of obstetric pregnancy, the level of hCG has stabilized and remains at the same level practically until birth.
How does hCG level change
In the blood plasma, an elevated level of hCG in pregnancy is monitored as early as on the 9-10th day after ovulation. If, for example, a couple was planning a child and was following the phases of the cycle, already 5-6 days before the expected date of the beginning of menstruation a woman can pass the first analysis. Chorionic gonadotropin is processed in the kidneys and excreted from the body along with urine. The principle of operation of pharmacy pregnancy tests is based on this fact. Their most simple and inexpensive models give an accurate result already 28-30 days after the onset of the last menstruation. More sensitive electronic tests can be used even before the delay.
Normal dynamics of growth and reduction of hCG levels during pregnancy allows you to control its progress at different times.
HCG on the 2nd week of pregnancy
The second actual week of pregnancy usually falls at the very end of the current menstrual cycle. With its duration of 28-30 days, ovulation was supposed to take place for 12-15 days. If at this time the egg meets the sperm, you can talk about conception. Within several days, as a rule, no more than 3-5, the embryo formed during the confluence of the germ cells, continues to move from the fallopian tubes into the uterine cavity. There, it begins to implant: the chorion villi of its shell grows into the endometrium softened by hormones, due to which exchange processes between the mother and the fetus are triggered. It was at this time that the synthesis of human chorionic gonadotropin is activated. Without pregnancy, the level of hCG does not exceed 1.5-5 mMe / ml. On the 9-10th day after ovulation, its maximum concentration can be 5.3-13.1 mMe / ml, on the 12th day - from 20 to 59 mMe / ml.
Pregnancy tests respond to a certain level of hCG
What hCG on the 2nd week of pregnancy? Normally, 14 days after ovulation, i.e. around the end of the current menstrual cycle or on the first day of the delay, the level of human chorionic gonadotropin can vary from 50 to 300 mMe / ml. Thanks to this, it can be “recognized” with maximum accuracy by any pharmacy test with a sensitivity greater than 25 mMe / ml. Three-digit numbers in the blood test for hCG also confirm pregnancy.
HCG in the 4-5th week of pregnancy
The 4th-5th obstetric week of pregnancy coincides with the age of the embryo at 2-3 weeks. At this time, the blastocyst within which the embryo develops has already been implanted in the uterus and is rapidly developing. At the same time, the process of formation of the placenta begins, the uterus becomes round - this can be noticed by the doctor during palpation and the ultrasound diagnostician during the examination. The delay on such a period exceeds 5-7 days, so any woman who has an idea about the duration of her menstrual cycle will probably think about pregnancy.
It is almost impossible to determine the absolutely exact dates of a real pregnancy, since it is impossible to find out the specific day when the egg connected with the sperm and the embryo entrenched in the uterus. That is why in most tables with hCG rates by week of pregnancy a rather large range of possible indicators is indicated.
In the first weeks, the hCG level doubles every two days.
Thus, the norm of hCG on the 3-4th week of pregnancy averages 2000 mMe / ml, and the tolerance limits vary from 1,500 to 5,000 mMe / ml.
The average level of hCG in the 4th-5th week of pregnancy is 20,000 mMe / ml, with an acceptable range of 10,000-30000 mMe / ml. On the 5-6th week, the corresponding norms are within 20000-100000 mMe / ml.
HCG level at 6-7 week of pregnancy
At the 6th obstetric week of pregnancy, the uteroplacental blood flow is actively formed, by the end of this period, the baby's heart is already beating. On the 7th week, due to hormonal and physiological changes, early signs of pregnancy - toxemia, weakness, high fatigue, impaired performance and other subjective sensations make themselves known. Many of them are associated, among other things, with an increase in the level of human chorionic gonadotropin, which helps the development of the placenta.
At the 6th-7th week of pregnancy, the rate of hCG is in the range of 50000-200000 mMe / ml. An analysis of this hormone can be prescribed in the event that it is necessary to verify the correct course of the pregnancy, since it is in the next 4 weeks that the fetal development is fading.
HCG helps placenta develop
HCG on the 8th week of pregnancy
By the end of the second obstetric month, the baby from one cell grows into an embryo with a complex device of the body - it already has a brain and spinal cord, as well as the cerebellum, eyes and ears are distinguishable, rudiments of limbs with joints are formed. In the woman's body, too, various changes are continually taking place: the uterus increases to 8 cm, the mammary glands become more sensitive, hormones still affect health and toxemia. The development of the placenta during this period is accelerated, along with this, the concentration of chorionic gonadotropin in the blood plasma and urine continues to increase.
So, at the 8th week of pregnancy, the level of hCG can vary from 40,000 to 200,000 mMe / ml. Such record figures may persist for 1-2 weeks, after which the level of the hormone will gradually decrease.
The rate of hCG in the 12th week of pregnancy
At the end of the 3rd obstetric month of pregnancy, the placenta is gradually included in the work, it takes more and more functions related to nutrition and protection of the baby, so the level of human chorionic gonadotropin becomes less and less every day. The average for the 12th week of pregnancy is considered to be 55000 mMe / ml, and the tolerance limits are 27500-110000 mMe / ml.
Hcg levels by week of pregnancy: reference table
The rate of hCG for weeks in the first half of pregnancy is as follows:
It is necessary to understand that only a specialist can interpret the result of the analysis. These figures can not be called reference, and when deciphering it is necessary to build on the health characteristics of a particular woman. The gestation period according to the hCG table can only be determined conditionally, and it will be more correct to calculate the DA according to the analysis results and the chorionic gonadotropin calculator, on the last day of menstruation.
More accurate results of gestational age for hCG can be obtained by women who have used IVF. In this case, the counting is carried out from the day of transfer of cultured embryos of different ages or from the day of puncture.
Table of hCG for days with pregnancy with IVF
Overpriced beta-hCG in pregnancy
Evaluating the level of hCG in the dynamics, the doctor can monitor the course of pregnancy. Sometimes it happens that this indicator is significantly greater than the upper reference value for the term. In this case, you need to check:
- multiple pregnancy with two or more embryos,
- lack of fetal chromosomal pathologies and other developmental abnormalities,
- trophoblastic tumors,
- diabetes in a pregnant woman.
In a double test of the first prenatal screening, when hCG rises during pregnancy, an additional examination is carried out. It eliminates the trisomy of the 21st chromosome and the associated Down syndrome. If you suspect a similar pathology, HCG is almost 2 times overestimated, and the bridge of the nose cannot be visualized by ultrasound.
HCG, several times higher than the level of 500000 mMe / ml, may be a signal of a threat to pregnancy - if there is a strong detachment of the ovum and there is a risk of fading fetal development. Another pathology in which the concentration of human chorionic gonadotropin is below normal is the so-called cystic skid, in which part of the chromosomes are “expelled” from the ovum. Such a serious condition can cause many delayed problems, including metastases and choriocarcinoma. If extremely high levels of hCG are detected at the beginning of pregnancy and for a number of associated symptoms (uncontrolled vomiting, uterine bleeding, pre-eclampsic symptoms, etc.), it is necessary to apply for emergency medical care as soon as possible.
Why can there be a high level of hCG?
Why does hCG level decrease?
Low levels of hCG in the early stages can be a symptom of a number of problems during its course. Insufficient concentration of this hormone often accompanies the development of Patau and Edwards syndromes in the fetus. Also, a weak increase in indicators may be due to the implantation of the embryo not in the uterus, but in the fallopian tube. Ectopic pregnancy is a dangerous condition that can not only harm the reproductive health of a woman, but also be a threat to her life. This condition is diagnosed with transvaginal ultrasound, when the fetal egg in the uterus is not visualized.
HCG in early pregnancy can drop dramatically during anembryonic and antenatal fetal death. Pregnancy triggered by various factors. If we are talking about chromosomal pathologies, the non-viable embryo stops developing, as a rule, until the 10th week. Also, such phenomena can be the result of infectious diseases and advanced endometritis. Abnormalities in the structure of the uterus and thrombophilia, when blood clotting processes are disturbed, lead to malnutrition and subsequent death of the embryo.
Ultrasound on the 7th week of pregnancy
If you have not had an ultrasound before, then at week 7 you can do it.
The main indicator of embryo health at week 7 is its heartbeat. The tiny heart of the baby is already beating with a frequency of 100 to 160 beats per minute, which should register the ultrasound machine.
The absence of a fetal heartbeat at week 7 is an alarming sign that may indicate a missed abortion.
Your feelings on the 7th week of pregnancy
Your uterus in week 7 almost doubled compared with the “non-pregnant” state, but it is still in the pelvic cavity, so the tummy remains flat during this period. Because of the sprain of the uterus, you may experience nagging pain in the lower abdomen, on the sides or in the lower back. This is normal: more than half of women experience pain in early pregnancy .
You can run to the toilet more often, including at night. This is due to several factors: firstly, the enlarged uterus squeezes the bladder, and secondly, the volume of blood circulating in your vessels has increased (as early as 7 weeks of pregnancy, the blood volume increases by 10%, and by the end of pregnancy your body will times more blood than before pregnancy).
If a signs of toxicosis did not appear earlier, they may appear this week. Nausea, vomiting in the morning, aversion to certain foods or smell - all of this symptoms of pregnancy at week 7 .
Someone toxicosis is more pronounced, someone weaker. If you do not have toxicosis, you can only congratulate. This by no means suggests that something is going wrong.
The hormonal changes your body undergoes bring new sensations: your chest may hurt, your body temperature may rise slightly. This is normal in the 7th week of pregnancy.
Many pregnant women note that discharge at 7 weeks have become more abundant. This is completely normal and is due to the fact that more blood flows to the genitals. Pregnancy excretions may have a transparent or slightly yellowish color. In this case, the discharge does not smell, or the smell is barely noticeable.
There are several symptoms that are a reason for going to the doctor at this time:
- Bloody (brown, pink, beige, red) discharge. Smearingdischarge in early pregnancy наблюдаются почти у каждой четвертой женщины. В большинстве случаев они не говорят об угрозе выкидыша или о выкидыше, и поэтому не требуют срочного обращения к врачу. Тем не менее, вы должны сообщать своему гинекологу о любых выделениях, которые кажутся вам подозрительными. На нашем сайте есть отдельная статья, посвященная этой теме: Месячные на раннем сроке беременности .
- If the discharge is sufficiently abundant and more like menstruation or bleeding, then you need to visit a doctor as soon as possible, or call an ambulance. Bleeding at week 7 Pregnancy can be a symptom of ectopic pregnancy. miscarriage and other complications.
- Severe pain in the abdomen, in the side or in the lower back. As we have said, small pulling pain in early pregnancy is normal, but if the pain intensifies, then consultation with a doctor is simply necessary.
Twins in the 7th week of pregnancy
According to statistics, a twin pregnancy occurs in every 90 pregnant women, and a triple one in each 8,000! Surely you are surprised and wondering “why and how did this happen?” Medicine is still unable to answer the question why some women are more prone to multiple pregnancies than others.
It is noted that twins and triplets occur more often in women older than 30 years, in women in whose family twins were born before, as well as in women treated for infertility (for example, after stimulation of ovulation on the background of polycystic ovary).
Features of pregnancy with twins:
- In pregnant women are twins manifestation toxicosis often more pronounced.
- Since the uterus grows faster in multiple pregnancies, tummy may appear somewhat earlier than those who expect one child.
- HCG level you will have a higher for your gestational age.
Tips for the future mom
In the next 2-3 weeks you should register on pregnancy. To do this, make an appointment with a doctor in the antenatal clinic.
You could have a lot of questions, and in order not to forget everything when meeting with the gynecologist, write your questions on a piece of paper or in a notebook in the phone.
If you didn't give up blood test for TORCH infection at the planning stage of pregnancy, it is desirable to do it now, or at least until the 12th week of pregnancy. A blood test for the infection will tell you if you are immune to rubella. cytomegalovirus. toxoplasmosis and herpes virus. These infections are especially dangerous if a woman becomes infected during pregnancy, so it will be very useful for you and your doctor to know in advance what to fear and what not. On our site there is a separate article on this topic: Blood test for TORCH infection. Your doctor may also prescribe tests for syphilis, HIV infection, and viral hepatitis.
To make sure that you do not have bacterial vaginosis. thrush. or others inflammatory diseases vagina, the doctor will make a smear on the flora. This is especially important if you are concerned about the discharge with an unpleasant smell, itching or discomfort in the intimate area.
Tips for the future of dad
Pregnant women become suspicious, so they can “invent” symptoms and diseases for themselves, which are not really there. Treat this with understanding and try to soothe the pregnant. Repeat to her that you are both waiting for a healthy baby or baby.
Your beloved may be excited or even frightened by the upcoming visit to the gynecologist. Ask if she wants you to go to the doctor together. Do not forget that this is your child, so you have the full right to take part in the medical examination.
Table of norms hgch during pregnancy by week
HCG (Chorionic Gonadotropin) is a hormonal substance inside the body that produces the placenta after fertilization. In the first days of the formation of the embryo, the amount of the hormone reaches its peak, but already in the middle of the first trimester, its amount begins to decrease.
Pregnancy test. Did you know that it is hCG that makes it possible to detect pregnancy in the early stages, and not only with the help of biochemical analyzes, but also with the usual pharmacy test. The pregnancy test is sensitive to the content in the urine of gonadotropin, and with a high content of it shows a positive result.
Fact. If you decide to be tested for pregnancy with a test a few days after intercourse, it will give a false option. Use the test can only be 10-14 days after the delay of menstruation.
Sometimes pharmacy tests provide false information about pregnancy. There are many reasons for this. First, the development of cancers of the genital organs, brain, mammary glands. Secondly, if you are being treated for infertility, some components of drugs can raise hormone levels. Thirdly, an abortion, an unsuccessful pregnancy at first retain the indicators of hCG until the woman's menstrual cycle is established.
Why do we need a table of norms hgch during pregnancy by week, what role does the hormone play?
Gonadotropin plays a major role in pregnancy - it prevents the onset of menstruation throughout the 9 months, also increases the level of hormones that help it to flow without complications, ensures its preservation until the birth of a healthy, full-term baby. In addition to these functions, it also reduces the immune system so that a miscarriage does not occur (rejection by the immune cells of the fetus), prepares female genitals for bearing and giving birth to a child.
Why is it necessary to control the level of hCG in the table?
Becoming a future mother requires a lot of attention, control from the woman. Now difficult childbirth, developmental abnormalities, genetic diseases can be identified already in the first, second semester.
Analysis of the level of hCG is considered one of those that should be monitored.
Hgch during pregnancy, the rate for weeks, the table - why is it so necessary to monitor all of this:
- Detection of pregnancy. At conception, a sharp jump in the hormone is observed, its quantity increases 10 times. Its high level is noted not only in blood, but also in urine,
- Suspected complications - ectopic pregnancy, miscarriage and bleeding,
- Informing about the healthy growth and development of the baby, the absence of pathologies.
What shows the lack of chorionic gonadotropin in the expectant mother:
- The discrepancy between the present period of pregnancy and diagnosed
- Ectopic pregnancy
- Stopping the development of the fetus, stopping its development,
- The threat of miscarriage and bleeding,
- Replantation of the fetus. The real term of the birth of a child has already passed, but this did not happen,
- Chronic placental insufficiency,
- Death of the fetus in the middle of pregnancy
- The threat of rupture of the placenta.
What threatens a high level of human chorionic gonadotropin in a pregnant woman:
- He reports twofold - the amount of the hormone increases with the number of embryos,
- The difference between the correct gestational age and the predicted,
- The development of genetic diseases that are associated with the addition of an extra chromosome or the absence of the necessary pair. For example, the development of Down syndrome (violation of the 21st pair of chromosomes),
- Signals the use of synthetic steroid hormones,
- Diabetes in a pregnant woman.
Immediately it is not advisable to test for hCG; even laboratory tests will not show a positive result for pregnancy if less than 10 days have passed from the cessation of menstruation.
The level of hormone in the blood / urine is determined by the weeks from conception.
How to prepare for the analysis of hCG: what to do, how is it carried out?
A biochemical blood sample is usually taken to identify the amount of this hormone. Although urine can give a positive result for the maintenance of gonadotropin, it serves as a qualitative rather than a quantitative indicator, i.e. it is suitable for determining the fact of pregnancy, but for detecting anomalies, monitoring it is not.
The cooking procedure. Do not eat before donating blood for at least 2-3 hours. To make the sample easier to take, drink a few glasses of water. Stop taking any drugs for three days before the procedure - they can affect the results of tests, in addition, some of them may be prohibited during pregnancy. If you can not refuse them, talk to your doctor.
Indicators of hCG in the 5th week of pregnancy: the norm, what does its violation indicate?
At week 4 of the preceding fifth gonadotropin is weak, therefore gynecologists advise not to concentrate on any figures at this time. The fifth week can already be considered indicative, but as long as it has not come, you can relax, eat more fruits and vegetables, and rest.
The next hormone, hCG, is added to estrogen and progesterone. It serves as a signal for the onset of pregnancy. In most cases, it is taken at 5 weeks to check for pregnancy.
It is during this period that it is worthwhile to follow its indicator especially carefully, because in the early term any indicators are easier to correct.
How much should HCG be on this period? The average value is 4 0900 in honey / ml, the norm is considered to be the range from 2 5800-6 5000 mU / ml. During this period, there is an active daily growth of the substance in the body.
How does a high level of hCG affect a woman during this period, is it felt? First, the appearance of a woman changes - a pleasant blush appears on her cheeks, she has a sparkle in her eyes, feminine beauty is emphasized, and her facial features are exacerbated. Secondly, appetite increases, sense of smell sharpens, taste preferences change - body mass index rises.
If the level of the hormone grows too slowly or stands still during this period:
- There is a risk of ectopic pregnancy,
- There is a threat of fetal death, stopping of its development,
- This indicates problems with the placenta.
If it was possible to identify the terrible anomalies with the help of hCG, what do the doctors do? When an ectopic pregnancy needs maximum control, more rest, an obstetrician-gynecologist will take the child by cesarean section. When the fetus fades, the development stops, the only way out is abortion.
What indicators of hCG are considered the norm in the table in the period from 6-8 weeks?
At week 6, the hormone grows with the same high progression. The heart of the baby is actively beating - this is an occasion to be even more attentive to the results of the tests.
What is considered normal in week 6? 1110 - 31500 IU / ml in the blood - is considered the limit of the normal course of pregnancy.
In what ranges should a hormone be at week 7? From 5,000 to 20,000 IU / ml
Indications for analysis on hCG at week 7:
- Suspected Ectopic Pregnancy
- The threat of miscarriage - measures to preserve pregnancy, to monitor the condition of the body,
- Suspicions of neoplasms.
What can say a deviation from the norm at this time:
- On the development of genetic diseases,
- About intense toxicosis,
- About twins or triplets - multiple pregnancy,
- Improper development of the fetus,
- Possible miscarriage, pregnancy complications,
- Rupture of the placenta.
The rate at week 8: 27000 - 230000 mU / ml in the blood.
A decisive period of 9-11 weeks or a sharp break in the index of gonadotropin in the table
This time plays an important role in the development of the fetus, during pregnancy. It is after him that a decrease in the hormone is noticed, women notice changes in their state of health.
HCG and toxicosis. The hormone is responsible for the manifestation of toxemia (nausea in the morning, sensitivity to odors, slight dizziness) Therefore, at the beginning of pregnancy, when gonadotropin is at its peak, there is a strong toxicosis after 11 weeks, it goes to no.
If you have changes upward at week 9, it sometimes signals an incorrect determination of the duration of pregnancy. Just retake the analysis after the time prescribed by the doctor, go through additional diagnostics - ultrasound. The rate is 20000-100000 mU / ml.
At week 10, the amount of the hormone reaches 46500-186396 mU / ml. Either this or week 11 is marked by the highest level of the hormone, which then goes into a state of decline. The well-being of a pregnant woman improves with it.
At week 12, the figures are falling. The minimum level is 13000 mU / l, the maximum 170000 mU / l. The tendency to increase and decrease is changing if you have a multiple pregnancy, so you should not panic right away if you are different from the norm.
What happens to hCG at week 13 of pregnancy?
At week 13, indicators are observed in the framework of 13000-60000 mU / ml. About what is happening with human chorionic gonadotropin at the moment, you can still judge by blood analysis.
This period - the period of the formation of organs, the heartbeat of the child on ultrasound is already clearly heard. At this time, biochemical laboratory blood tests will help you find out whether genetic abnormalities are observed, whether the baby is developing normally or not.
If there is any difference in the numbers of human chorionic gonadotropin, do not immediately worry. Only after passing a full examination, appointed by an obstetrician-gynecologist, will allow you to fully assess the situation.
In order for the results of the analysis to be accurate, the slightest error was excluded - do not exercise a day before donating blood, do not take hormonal preparations, refuse to eat a few hours before the procedure.
How does pregnancy develop at week 18: hCG levels
The level of eighteen week chorionic gonadotropin is in the range from 4000 to 165000 mU / ML. A drop in the amount of this substance does not always report pathologies at this time. Some expectant mothers have deviations downward and at the same time give birth to a healthy baby without a cesarean section. But if the indicator has begun to rise strongly, it is necessary to urgently go through a comprehensive diagnosis and take appropriate measures when any deviations are detected.
If you were suddenly asked by an obstetrician-gynecologist to donate blood for this hormone - do not worry. In the middle of pregnancy, the doctor must make sure that everything is normal with the child, there are no deviations. In addition, obtaining information about the state of the body of the future mother and child helps to decide on what method to take birth, they will be heavy or ordinary.
What are the levels of hCG a few weeks before delivery?
From week 23 and before childbirth, a single hormone normal range is defined: from 2500 to 78000 mU / ml.
A change in this indicator may signal a peerable pregnancy (when the child is not born on time), the main solution to the problem for doctors is a cesarean section. Before that, a comprehensive examination is carried out (it is necessary to find out how the fetus is located, whether it is not wrapped with an umbilical cord), preparatory measures are taken before artificial birth.
If there are sharp jumps in the 37th week of pregnancy, premature labor can begin. The main task of doctors is to provide all the conditions for the normal functioning of a premature baby. Sometimes a premature baby can suffer from various pathologies, genetic changes. Therefore, he is under special observation.
Can anything be done to bring hCG back to normal?
Sometimes hCG is not the cause, but an indication that the pregnancy does not go as it should. Therefore, it is necessary to deal directly with the cause - genetic disorders, placental insufficiency, the threat of miscarriage.
Is it possible to raise chorionic gonadotropin? Synthetic steroid hormones increase its quantity, but can harm the child. Because you can not calculate the interaction of a given amount of hormones, as a result, the hormone will be greatly elevated and threaten pregnancy.
Does chorionic gonadotropin decrease in an artificial way? The procedure of lowering the doctors never do. Because if there is a threat of rejection of the fetus during an increase in the hormone (immune cells begin to work actively again) or problems arise with the placenta and uterus (the hormone prepares them for the birth of the child - it expands, increases the blood flow), then the decrease speaks of something else.
