Norms and methods of ultrasound at 6 (8 obstetric) week of pregnancy

In the eighth week of pregnancy, the belly is not noticeable, however, the expectant mother feels her interesting position very well. At this time, women need to especially carefully monitor their health, as there are certain threats.

What happens to a woman in the eighth week of pregnancy

To be honest, the condition of a woman during this period can hardly be called beautiful. Despite the joyful experiences, there are a lot of unpleasant feelings on the physical level. It all starts with the constant desire to urinate, which is only increasing by the eighth week of pregnancy. Toxicosis still accompanies the future mother, but begins to be transferred easier. During this period, the abdomen is not noticeable, however, suddenly increased oily hair and skin are noticeable. This is not very pleasant, because with it appear eels on the face. Although in some cases, by increasing the level of stem cells, everything happens exactly the opposite: the skin condition is noticeably improving, becoming cleaner. So pregnancy affects all women differently.

Fetal size in the eighth week

During pregnancy, a week of pregnancy is a whole epoch for a woman in an interesting position. The future mother wants to know the details of the development of the fetus, what size it has, what it looks like. During this period, the baby is still too small. The photo on the ultrasound shows that its growth is no more than 22 mm, and its weight is about three grams. During this period there is a straightening of the fetus, which was previously in the form of an arc. If you pass the ultrasound, you will see in the photo that the head of the fetus has a clearer outline, like the whole body, arms and legs. The second month of pregnancy is the time when the tail disappears. The baby becomes more active and, at times, can change its position. However, the mother still does not feel his body movements in the uterus, because the size of the fetus is very small.

For a period of two months, the baby slowly acquires the features of a real person: on ultrasound, you can see the eyes, nostrils, and even ears. When the eighth week comes to an end, the nature of the development of the face of the fetus is even more intense - the eyelids and nascent primordia appear, the smell organs and taste organs are laid. The activity of the baby is partly explained by the fact that his joints have become much more mobile, because bone tissue is also actively forming. With regard to the development of internal organs, the child has already developed the gastrointestinal tract and pancreas. There is a rapid development of the nervous system of the fetus, so it is safe to say that the baby is feeling in the eighth week of pregnancy.

Changes in the body of the future mother

Many women already feel that during pregnancy begins to change their body. The size of the uterus increases and slowly begins to rise up. The size of her ultrasound on the photo a little more than a fist. The stomach is not noticeable yet, and only the expectant mother can feel that his slight bulging has occurred. You may also feel painful cramps, but you should not be afraid of it. They are a sure sign of the development of pregnancy according to the plan, but if the pain occurs frequently or is severe, you should immediately consult a doctor.

In the eighth week of pregnancy continues to increase breast. Areola nipples darken and visible blood vessels. So the mammary glands are preparing for the future feeding of the child.

Analyzes in the second month of pregnancy

As a rule, during pregnancy at the end of the second month - this is a real routine in terms of testing and bypassing doctors. Many women will find out that they will have a baby, precisely during this period, therefore, he has to take the first trip to the gynecologist. The success of the development of the fetus depends on how the expectant mother will take care of her health, as well as on whether she can put herself in time in order to cure minor diseases.

When it comes time to consult a doctor, many women do not realize how often they will now visit health centers. The gynecologist will write out directions for a complete blood count, as well as a blood test for HIV and syphilis, urinalysis, and chronic gonadotropin. The latter is very important for determining the development of the fetus and the correct course of pregnancy.

If the level of hCG is high, this may indicate the presence of twins. However, the same may indicate the presence of such a disease as diabetes mellitus, or indicate various pathologists of the development of the baby. Also, a high level of gonadotropin may indicate that the duration of pregnancy was incorrectly identified.

If hCG is too low, then this may be a clear indicator of frozen or ectopic pregnancy, placental insufficiency. Often he says that there is a threat of miscarriage or again malformations.

In addition to all sorts of tests that you have to take during the entire nine months, the doctor will measure your body: hips girth, abdominal volume and weight. The gynecologist will take smears from you and refer you to other doctors. For example, you will need to visit a dentist, general practitioner, laura, oculist and, if necessary, undergo a reorganization.

Second month of pregnancy: danger

Each of the pregnant women understands that the future of the baby depends on her health. However, many expectant mothers underestimate all the dangers that may affect the process of carrying and its result. It would seem that the usual ORVI does not cause you any fear. But not in pregnant women. Any infections that appear in your body will be passed on to the fetus or extremely adversely affect its development. The second month enters the first trimester, when the fetus is still extremely vulnerable.

SARS is a viral infection that can cause a malfunction in the development of a baby. In addition, its symptoms, such as fever, are extremely negatively affected. If you have a fever, miscarriage may occur. Therefore, in the event of a cold, in no case should you wave your hand at her and carry her on her feet. You need to consult a doctor so that he prescribes you the correct regimen and safe medications for her treatment. Antibiotics are contraindicated, and the temperature is allowed to fight only with the help of paracetamol, which, in general, is also not safe. However, if you find yourself running a cold, do not rush to panic. During pregnancy, the first trimester gestation week presents the most interesting surprises. Your nose can get stuck simply because progesterone levels rise, and it retains fluid in the body.

Thrush is also a problem. And it occurs at this time often, because in pregnant women reduced immunity. Do not try to treat it yourself, because in your position you need completely different medications.

If you suddenly suddenly have toxicosis, this is not good. This is possible, but keep in mind that this symptom is an alarming sign of missed abortion. Show it will help photo ultrasound.

Any bleeding is not a reason to panic, but a reason to talk with your gynecologist. Perhaps your uterus is in good shape. But it may also be a sure sign of an impending or miscarriage that is already occurring, depending on its course. Pay attention to pain. If they do not pass, and continue to pull the stomach, even if you lie down, this is also a symptom of miscarriage.

The second month of pregnancy is a period in which you should especially carefully monitor your body and note all the nuances that concern you.

Mom's food

The fact that the expectant mother eats, invariably affects the health of the baby. Therefore, priority is given to fruits and vegetables that grow in the territory of the country of residence or are habitual food. If you suddenly decide to discover a new fruit, consider whether it will cause an allergic reaction. It is very important at this time to consume as many foods with calcium as possible, because in pregnant women hair, teeth and skin are primarily affected.

Despite the fact that in the first trimester in the absence of toxicosis, you may feel a big appetite, you should not lean too hard on food, especially flour.

By the way, if you have observed toxemia with frequent vomiting, it can lead to dehydration. Therefore, in this case it is necessary to drink as much liquid as possible.

But the use of coffee and tea should be reduced or completely abandoned. The fact is that they constrict blood vessels, increasing the load on the heart. And this is extremely negative and responds to the expectant mother and child.

Ultrasound examination at this time is not mandatory. But the doctor can prescribe it to make sure that the deadline is correct, or to exclude his moments of concern regarding the development of your baby.

At this time ultrasound is carried out not only to find out the size of the fetus, but also to resolve all doubts about the correct pregnancy. If the doctor doubts that the pregnancy is uterine, he directs the woman to an ultrasound. Photo research clearly shows where the fetus. If in the uterus ultrasound does not show it, surgery will be needed.

For a period of eight weeks, a doctor can exclude a bubble skid on the ultrasound photo - a very unpleasant pathology, which is a childish place in which bubbles grow. This is fraught with the death of a child. The problem is that if she is not found in time, then the woman may not know that the fetus has died. After all, this process is not recognized in any way, and the pregnancy continues to proceed normally.

Ultrasound in the second month shows not only the image of the baby, but also determines how viable it is. The doctor determines this by the heartbeat and movements of the fetus. By the way, the frequency of contractions of the heart muscles at eight weeks of the fetus is 150 beats per minute. In addition, an ultrasound photo at this time may reveal some deformities as well as impaired development. Therefore, for many women, ultrasound in the early period is an extremely important study.

During pregnancy, a total of about three ultrasounds are to be done by women, however, the first is the most exciting one. Indeed, during the course of the study, you meet the child for the first time, see him in the photo and recognize his features.

Why do ultrasound at this time?

There are several reasons why a doctor may recommend an ultrasound scan:

  • a woman complains of feeling bad, she has a stomach ache,
  • Signs of toxicosis have disappeared,
  • there is a risk of missed or ectopic pregnancy,
  • Ultrasound is carried out on an emergency basis, when the patient has discharge of bloody nature,
  • if there were unsuccessful pregnancies (miscarriage or missed abortion).

At six weeks, studies are conducted with the goal of getting maximum information. Determine whether the fetus develops and exclude the likelihood of missed abortion. As well as research helps to eliminate the likelihood of an ectopic pregnancy.

The indications for ultrasound can be considered the results of blood tests for progesterone and hCG. If they have any abnormalities, then the gynecologist can send the woman for an examination in order to make sure that everything is in order with the future mother and her child.

It can be recommended to go through an ultrasound procedure when a woman becomes pregnant as a result of IVF or during stimulation. In this situation, the entire period of childbearing will be held under the close supervision of specialists.

Mom's condition and how pregnancy develops

Week 6 is considered almost the very beginning of pregnancy, at this stage a woman can guess her position by the following symptoms:

  1. Increased breast sensitivity. Not only the mammary glands, but also the nipples are extremely sensitive. When touching the chest, you can feel a strong, bursting pain.
  2. Changes in the quality of the skin. The woman has acne, they can be localized on the face, the skin becomes more loose and sensitive to allergens, chemicals and cosmetics.
  3. The well-being of the future mother changes, she becomes more capricious. A woman is worried about weakness, she experiences irritation, and problems with sleep can occur. And the reason for all - unstable hormones.
  4. Changing the taste of food, there is a sharp reaction to the smell. Attacks of toxicosis may be disturbed, strange taste preferences may arise.

At this period, pregnancy is developing with might and main. In the body, hormonal changes are occurring and corresponding changes occur. The uterus of the woman may exert a slight pressure on the bladder, there are frequent urge to urinate, which have no connection with diseases of the kidneys or bladder.

In the sixth week of the baby, the formation of muscle tissue occurs, and blood begins to circulate throughout the body of the baby. The embryo's brain and spinal cord are formed from the fetal neural tube.

What will the diagnosis show?

When conducting research in the early period, many moms think that an ultrasound scan will help them know the sex of the baby. But it is not.

The doctor will pay attention to:

  • possible pathologies in fetal development,
  • possibly already having a fetal heartbeat,
  • embryo visualization
  • the subject of the presence in the womb of one or more fruit eggs,
  • exact location in the uterus of the ovum.

Looking at the monitor, the future mom will see her baby. It will resemble a pea or a small dark spot. In this case, you can consider the legs and handles. The child has poorly developed eyes at this stage of pregnancy, for this reason they will be tightly closed.

The specialist will study the fetus, its internal organs, as well as help to eliminate possible defects in the work of the heart, liver and other organs.

And at this time a happy mother can find out about what she expects twins.

How do?

Research on this period can be conducted in two ways:

  1. Ultrasound through the anterior abdominal wall. This procedure is considered less informative, but more secure. In addition, not all medical institutions are equipped with the appropriate equipment to conduct research by another method.
  2. Transvaginal ultrasound with the introduction of a particularly sensitive sensor in the vagina of a woman. It has high accuracy, is used in the absence of contraindications. It helps not only most accurately determine the duration of pregnancy, but also the presence of pathologies in the fetus, which is extremely important.

If we talk about the examination, which is carried out through the anterior abdominal wall. That it is not much different from any other procedure ultrasound. A woman is placed on a couch, a highly sensitive gel is applied to the abdominal area and an ultrasound is diagnosed. The specialist will talk with the patient, report on the condition of the fetus, at the end of the procedure will issue an opinion.

Ultrasound using a transvaginal transducer is a bit different. The woman lies down on the couch, the doctor processes the sensor with a special antiseptic, puts a disposable condom on it and inserts the woman into the vagina.

An image appears on the monitor screen, the doctor determines the fact of pregnancy, examines the fetus for the presence or absence of developmental pathologies. Upon completion of the procedure gives the woman a conclusion.

Going to the survey with you must take:

  1. Direction to ultrasound (if any).
  2. Medical card pregnant.
  3. Clean diaper or large towel.
  4. Slippers or shoe covers.

You also need to stock a certain amount of time, since the procedure will take from 10 to 15 minutes.

How to prepare?

Preparation for the procedure depends on the method of the ultrasound scan and goes through several stages:

  • preparation of the intestine for examination,
  • hygiene procedures before visiting a doctor,
  • filling the bladder with water to get accurate results.

2-3 days before ultrasound diagnostics, it is worth refusing to eat foods that lead to excessive gas formation in the stomach. Spices, legumes, soda, etc., should be excluded from the diet.

Before you go to see a doctor, it is recommended to take a shower. Conduct hygiene procedures genitals.

This is especially true for those patients who are to conduct ultrasound transvaginal method.

In the first trimester, the study is recommended to carry out with a full bladder. Before the procedure, it is advised to drink about 500 ml of pure water. This will help to see the fetus and uterus better, but in some cases it is not necessary to drink water. For this reason, it is worthwhile to clarify this with the attending physician or nurse.

Who is recommended to study at this time?

Some women self-register for ultrasound at week 6, trying to find out about their “interesting position” in this way. But it is better to go to the study after the recommendation of the doctor.

Ultrasound examination is performed:

  • in the case of IVF,
  • to register a woman for pregnancy
  • in the presence of suspected frozen or ectopic pregnancy,
  • urgently with the threat of miscarriage.

In spite of the fact that the procedure is not included in the list of planned ones, it is not worth holding it out of the ordinary. Порекомендовать сделать УЗИ пациентке врач может в том случае, если возникла путаница со сроками или женщина самостоятельно настаивает на проведении исследования.

When appointed

Ultrasound examination at 8 weeks of pregnancy is carried out in exceptional cases. Usually the first diagnosis is appointed not earlier than 11 weeks. Early screening is carried out in the following cases:

  • to identify the fact of pregnancy
  • exceptions to the presence of formations in the pelvis, often imitating pregnancy,
  • clarification of the location of the ovum,
  • exclude or confirm the fact of ectopic pregnancy
  • to detect pregnancy twins,
  • clarify the duration of pregnancy,
  • detection of obstetric pathology, elimination of missed abortion,
  • eliminating the risk of miscarriage,
  • identify fetal abnormalities.

How is the procedure

Many women are interested in how to diagnose, above or inside. A transvaginal examination is usually done for a period of 7–8 weeks, since the diagnosis performed abdominally does not always accurately show the size of the fetus. During the diagnosis of the vaginal sensor does not require special training. However, in order to get the most accurate results on ultrasound, the following conditions must be met.

It is important to empty the bladder. This condition is significantly different from the abdominal examination. It requires maximum fill the bladder, after drinking at least 1 liter of fluid before the procedure. In the intestine should be no gas. In order to better see the condition of the fetus, a special diet is appointed, which excludes the intake of a diet that increases gas formation and the use of medications, such as activated carbon.

Late transvaginal ultrasound can lead to miscarriage. Often, women are wondering whether it is possible to do an internal examination if there is a threat of miscarriage. In this case, the doctor conducts abdominal diagnosis.

What determines

At week 8, the child's heartbeat is set by ultrasound, which should be in the range of 110–130 beats per minute. If a heart rate of less than 100 beats per minute is determined, this is not considered favorable. This condition requires immediate treatment. Since it is a direct sign of the development of an intermittent pregnancy. This period allows you to assess the presence of activity crumbs. During the procedure, the movement of the head is recorded.

In addition, the condition of the fetus is estimated by the magnitude of the CTE. It should be about 17 mm in size, the parameter of the ovum should not exceed 28 mm. A term of 8-9 weeks implies a baby in the lower part of the uterus.

Although the child in this period is no longer an embryo, but nevertheless he still has a physiological hernia, characteristic of the embryonic period. An embryonic hernia appears to be damage to the abdominal wall through which intestinal loops exit.

In the eighth week, the yolk sac can be monitored, which makes it possible to predict the presence of complications. The yolk sac is an intermediate organ, determined only until the second trimester. It is precisely by its condition that the possibility of spontaneous miscarriage is determined. These complications can be determined:

  • with a reduced size, less than 2 mm,
  • the increased parameter is greater than 5.5 mm.

Ultrasound is used in the diagnosis of missed abortion. The criteria for this pathology are:

  • absent heartbeat of the fetus,
  • missing motor activity
  • the presence of anembryonia, represented by an empty fetal egg.

Decryption

After the procedure, the woman receives an examination report with the designated parameters. First of all, the presence of the ovum will be indicated. During the procedure, its shape is carefully studied. Fetal egg should be without deformation, its size is in the range of 24-30 mm. The norm is represented by the following average egg sizes:

The content of the article

The female body changes throughout the duration of pregnancy. The failure that occurs against the background of the birth in the mother's womb of a new life, affects the mechanism of vital activity of the whole organism. As a result, as time passes from the moment of actual conception, the patient in the position can acquire new sensations and change her habits. Each subsequent week of embryo development is characterized by its own characteristic changes, which allow to judge the state of pregnancy. And today we will tell you about the symptoms of the eighth week of pregnancy, what can be seen in the ultrasound photo in this period, and how to recognize the symptoms of hazards at this time.

First of all, to avoid confusion, it is worth mentioning that the eighth obstetric week is the 6th embryonic week of pregnancy. This seven-day period coincides with the fourth week from the beginning of the delay in menstruation and is the final for the second calendar month from the moment of conception.

Physiological changes

For the development of the fetus, the eighth week is an equally important period. The second month of pregnancy is coming to an end, and at this stage of the embryo’s growth, its main organs are laid, which constitute the mechanism of the baby’s life. Although each organism is individual, during the eighth week of pregnancy external signs and internal changes become more pronounced. In the photo of pregnant women, a slightly rounded tummy is already becoming noticeable, and even those who somehow have not found their pregnancy up to this point will be able to experience all the signs characteristic of this state.

The 8th week is the optimal time to consult with the gynecologist, to be registered in a medical institution and to undergo the first ultrasound scan. According to the results of the examination of the future mother, the doctor will be able to present the first photo of the baby, on which it will be possible to examine its location and the images of the head, torso and limbs. At the time of the first examination by a specialist, the pregnant patient will be announced the date of the expected birth, taking into account the size of the fetus and the last monthly discharge.

Embryo at the end of the second month

Six weeks have passed since the actual conception, and this obstetric seven-day period is marked by an intense transformation of the embryo. Although the patient's tummy is still small, the pace of fetal development is simply amazing.

At this stage of fetal growth, it is already possible to clearly see whether everything is in order with him. As a rule, in the first session of the ultrasound the specialist voices the existing organs and their description. By the time of the eighth week of pregnancy are already seen:

  • all the limbs with tabs on each of them,
  • fetal head with eye pits and type of ears.

According to studies, for a period of eight weeks the baby in the womb is the size of a grape berry. Its weight during this seven days varies in the range of 2.5–3 g. By the end of the second month, the length of the fetus can reach 1.4–2 mm. As you can see, from the moment of conception a phenomenal breakthrough in the development of the embryo occurs, which is confirmed by similar data and photos of the ultrasound of this period.

What has changed since the last week in a small body?

Since the last seven days, when the eighth obstetric week of pregnancy begins, the size of the fetus changes. This happens against the background of the rapid development of the fetus and its extra-fruitful space.

Although, as shown by numerous photos of pregnant patients, the tummy is not very noticeable at this time, very rapid processes take place inside it. The embryo develops, and during the eighth week you can observe:

  • the division of the brain of the embryo (3 divisions appear),
  • the formation of large joints and fingers on all limbs of the fetus,
  • gradual modification of the tail,
  • the initial stage of intestinal formation, part of which is located in the umbilical cord,
  • the innervation of some muscles, which allows the implementation of motor impulses,
  • branching bronchus,
  • the formation of primordia of the future genitals,
  • enveloping the muscular tissue and salivary glands of the oral cavity walls,
  • formation of the peripheral nervous system.

Also visible and changes in the facial part of the embryo. For a period of eight weeks, during an ultrasound examination, you will see future facial features. In this time interval, the ears, eyes and nose are formed, which at the moment will be still closed.

One of the most important events of the end of the second month of pregnancy is the beginning of the functioning of the tiny heart. Now it is almost fully formed and consists of four cameras. By the time the eighth obstetric week of the “interesting position” arrives, the crumbs of the heart work by sending blood through large vessels. In addition, in this period of prenatal development in the small body the blood circulates in two streams - arterial and separately venous.

Genital System Changes

Having learned about her pregnancy, on the 8th week many patients cannot wait to find out the sex of their offspring during an ultrasound examination. However, in this period, the development of the genitals undergoes only the initial stage of formation. Now the future organs are only being laid.

With a more detailed study of the fetus, you can only see the sex rollers, from which the corresponding organs are formed later.

During the eighth week, the ovaries are laid in the female embryo, in the cortex of which the ovarian reserve with follicles is formed. At the time of the formation of the genital organs of the female fetus, the number of follicles reaches 7,000,000. From this time until the birth itself, there will be a “rejection” of defective cells, resulting in an ovarian reserve of approximately 1,000,000 follicles. Their number will decrease during the first 13–15 years of the girl and at the time when the first brown menstrual discharge begins, about 250,000 cells will remain full-fledged cells.

As for male embryos, at the 8th week of their intrauterine life, testosterone begins to be produced. By the end of the second month, in the tiny bodies, the testicles are laid. This period is very critical for the male fetus, since if a full-fledged SPY gene is not found on the short arm of chromosome Y, the development of the embryo stops. At this stage, the risk of miscarriage increases, so if a pregnant patient detects the beginning brown discharge with accompanying painful sensations, you should immediately contact your gynecologist.

How to describe your condition of the patient?

The eighth obstetric week proceeds with very pronounced signs. Therefore, many people during this seven days visit a gynecologist, undergo an ultrasound examination and become registered.

The surest signs of pregnancy are delay and toxicosis. A new condition for a woman may be accompanied by dizziness, as well as vomiting, which can occur no more than 2 times a day. In this case, the symptoms are considered normal. If the urge is very frequent and there is a strong toxicosis, in order to avoid complications, you should contact the doctor leading the pregnancy. Also deviations are painful impulse sensations in the eighth week of pregnancy, as well as brown uterine discharge. Such phenomena constitute a threat to the fetus.

General state

Not only vomiting, dizziness, nausea can lead a woman to the idea that she is pregnant. The first symptoms of the patient's new condition are also:

  • fast fatiguability,
  • drowsiness,
  • irritability,
  • emotionality

New sensations characteristic of the eighth week after conception, in the usual rhythm of life of the pregnant patient make significant adjustments. The symptoms of life originated inside (minor discharge, nausea, discomfort in the pelvic area, hypersensitivity, heartburn, tearfulness, etc.) make many people worry about it.

On the 8th week, the breast begins to increase more noticeably, its sensitivity increases, and tingling appears in the nipple area. It also gives a lot of inconvenience to the future woman in labor. To reduce discomfort, pregnant women can wear simple underwear and use towels made from natural materials. At the same time, the patient will have to get used to these sensations, because the breast will continue to increase as the duration of pregnancy increases.

Possible pain

In addition to the manifestations of toxemia and delay, a woman in the position may experience nagging pain in the lower abdomen or lower back. If the painful sensations are not impulsive in nature and are not accompanied by fever, brown uterine discharge, there is no cause for concern. Otherwise, the woman's body can signal the imminent danger, which requires consultation with a gynecologist.

In the early stages of pregnancy, including on the 8th week, pain can occur due to the restructuring of the female body. When enlarged to create extra-embryonic space, the uterus affects the nearby organs. As a result, the bladder is also impaired, resulting in a decrease in it and frequent urination. It should be noted that during the urination of pain should not occur. If there is a heaviness in the pelvic area and with a bowel movement, the woman experiences pain, discomfort, you should consult a doctor for advice.

Substances secreted from the uterus

Characteristic for early pregnancy are uterine discharge, if they are not intense and are "harmless" nature. Normal for the eighth week of pregnancy are considered substances:

  • light, not brown,
  • moderate,
  • with a slight sour smell.

Any change in consistency, hue or volume of discharge may be a signal of a pathological disorder. In such situations, you must consult your obstetrician-gynecologist.

A visit to the doctor should be urgent if the patient is in a position to notice brown discharge. In most cases, this symptom indicates the threat of detachment from the uterus of the ovum (miscarriage). The situation becomes dangerous if bleeding (heavy brown discharge) is accompanied by other factors:

  • cramping, impulsive pain in the lower abdomen or lower back,
  • dizziness,
  • rising body temperature
  • weakness.

In the event of such phenomena and signs, it is worth contacting a medical institution immediately so that the doctor has the opportunity to prevent adverse effects.

What tests and examinations do the patient expect?

As mentioned earlier, the eighth week of pregnancy is the best time to get registered in the antenatal clinic. At this stage, each patient who has addressed the gynecologist with the corresponding symptoms must undergo a mandatory examination.

When contacting the antenatal clinic against the background of the outbreak of pregnancy, women in the position expect:

  • examination by a gynecologist,
  • first ultrasound examination,
  • delivery of biological materials (urine, feces, blood tests - general and clinical),
  • delivery of a smear for cytological examination of vaginal flora.

In addition, when registering, pregnant patients will need to be examined by other doctors. According to the results of examinations and ultrasound scans, a pregnancy schedule will be drawn up from conception to childbirth.

Purpose of the survey

Mandatory ultrasound at 8 obstetric week is not considered. Before the first planned examination, screening of the first trimester, there are still about 3-4 weeks. However, even at this time the doctor may recommend a woman to undergo ultrasound diagnosis.

Many in this obstetric week for the first time turn to a consultation to get registered. Ultrasound may be necessary to clarify the pregnancy, if a woman, for example, does not know the exact period of conception or cannot remember the first day of her last menstruation.

There are other reasons why an expectant mother can be sent to the ultrasound diagnostic room at week 8:

  • Confirm the fact of pregnancy, if on examination the obstetrician-gynecologist doubted this (the size of the uterus on palpation is too small).
  • Make sure that the pregnancy is uterine, if earlier the woman had cases of ectopic pregnancy, miscarriages, missed pregnancies.
  • Make sure that the pregnancy develops if the woman has spotting, pain.
  • Clarify whether a woman has fibroids, cysts that could affect the delay in the absence of pregnancy.
  • Find out the number of fetuses, if the woman already had multiple pregnancies, as well as in the case of high levels of hCG in the blood.

Survey method and preparation

Ultrasound examination at such a short time (8 weeks by obstetric standards - this is only 6 weeks from the moment of conception) is carried out mainly by the transvaginal method. A woman is inserted into the vagina with a sensor in the condom. This method has a higher accuracy at an early date.than transabdominal ultrasound, in which the uterus and its contents are examined through the peritoneum.

If the ultrasound is planned, then it is desirable for the woman to prepare for the diagnosis.

A few hours before the doctor’s visit, you should take “Espumizan” or “Simethicone” to eliminate the accumulation of gas in the intestine, since swollen intestinal loops can squeeze the pelvic organs and distort the ultrasound results.

Пить много воды, чтобы наполнить мочевой пузырь, перед прохождением трансвагинального УЗИ не требуется. Наоборот, врач может попросить прийти с пустым мочевым пузырем для получения более четкого изображения.

Само исследование органов малого таза ультразвуком не доставляет женщине неприятных или болезненных ощущений, does not harm the unborn baby. It lasts about 5-7 minutes.

What will ultrasound show at week 8?

If a high-resolution device is installed in the ultrasound room, and the diagnostician will be so kind that it will show the future mother a monitor and explain what is happening there, then the woman will be able to see enough to understand that her little one has already passed a long evolutionary path. The ultrasound shows that the embryo has increased in size the head, it can be almost half of all sizes. The baby begins to form limbs, and the tail, which was before, no longer exists.

During this period, the formation of the eyes, eyelids, nose and lips, as well as the optic nerve begins, but all this cannot be seen on an ultrasound, the size of the unborn child is too tiny. But you can hear the crumbs heartbeat and see how the aortic valves are reduced in his already completely four-chamber heart. An ultrasound doctor will be able to record and assess the baby's physical activity, which the woman herself cannot yet feel due to the small size of the embryo.

Week 8 completes the embryonic period of development, already in seven days, the baby will no longer be called an embryo; it will officially become a fetus. Also during this period, the testicles form in the baby’s abdomen, if it is a boy, or the ovaries, if it is a girl. However, it is not yet possible to see the floor on ultrasound, because the embryo does not yet have external sexual characteristics.

In addition, the doctor will assess the state of women's health, note whether there is a threat of miscarriage, interruption, separation of the ovum from the walls, whether the uterine walls are homogeneous in their structure, the state of the ovaries, tubes and neck of the genital organ.

According to the parameters of the ovum and the embryo, he will be able to adjust the exact duration of pregnancy.
