Whether do or make US on 5 week of pregnancy? Ultrasound at 4, 5, 6 obstetric pregnancy week: what is visible?

The fifth week of pregnancy is the period with which most often come to be registered in gynecology. Usually the delay in menstruation at this time is not less than 14 days, now it can no longer be attributed to chance. Usually by this time, signs of toxicosis begin to show itself clearly. It can not be said that these are particularly pleasant moments, but this is the first trimester. It is ultrasound at the 5th week of pregnancy is the first documentary confirmation of this particular condition, so often doctors refer women to the first examination to resolve all doubts and make a diagnosis.

How much ultrasound is needed for this period

Usually doctors do not hurry to send future moms to the survey. The time is still very short, and there is absolutely no need to do ultrasound at the 5th week of pregnancy. However, sometimes very impatient mummies themselves are recorded for examination, which today can be done at any polyclinic, especially on a paid basis. Most of all, this concerns the category of women who have been waiting for pregnancy for a long time and want to get confirmation sooner that they really will become mums. Most often at such a short time the doctor will send an ultrasound if the woman wants to terminate the pregnancy. Therefore, if you are not worried about anything, there is no bleeding, severe pain, then it's better to wait a little, because the research at this time may not be too reliable.

What is the womb at this time

Externally, the future mother still does not differ from her friends, but miracles already begin to happen inside her. First of all, the uterus itself changes. Ultrasound pregnancy of 5 weeks confirms only if it is carried out on good equipment. However, an experienced doctor can determine the increase in the uterus itself. This is normal, because inside it is a fetal bladder larger than 1 cm. However, this increase is uneven: it is on the side where the embryo is attached to the uterus that it is protruding. Ultrasound on the 5th week of pregnancy is not very informative, so even an experienced specialist who works on good equipment will not be able to say much in addition to being a mom. When the image is enlarged several times, he will be able to determine the yolk sac and the embryo itself. Moreover, it is at this time that the baby's heart starts beating. In addition, at this time in the ovary, from which the ovum came out, the body is still noticeably yellow, which is evidence of an early pregnancy.

What is visible on the monitor

Far not always a woman undergoes ultrasound in a specialized clinic, where there is special equipment for three-dimensional ultrasound. And on a normal machine, no one but the specialist can figure out what he sees on the screen. Therefore, we must rely on the experience of the doctor. Ultrasound at the fifth week of pregnancy allows you to see the embryo itself, which is still very similar to a small cylinder. Its length is five millimeters, and the weight is only 3.5 grams. However, despite the fact that it is still very small, the most important processes take place within it that determine all subsequent development. Now the neural tube is formed, the respiratory system, the liver and pancreas are laid, the cells are formed, from which the male and female sex cells will later develop. On the monitor you can see not only the tail and the head, but also the rudiments of hands and feet, fingers and an eye. With the help of a special sensor the first heartbeat of a little man is listened.

The first measurements

Ultrasound at the 5th obstetric week of pregnancy allows for the first measurements and approximately determine whether the embryo is developing correctly. Measured the coccygeal-parietal size of the embryo, based on this, you can calculate the weight of the future child at birth. Necessarily the doctor will assess the position of the fetus in the uterus, the tone of the myometrium, the condition of the ovaries and the yellow body. In this case, the doctor on the monitor sees an enlarged uterus resembling an egg in shape. This asymmetry arises from the implantation of a fertilized egg into the thickness of the endometrium.

Movement of the embryo

It's amazing how many doctors can learn about a baby when the gestation period is 5 weeks. The ultrasound allows the doctor to draw a conclusion and about how actively the embryo moves. It is the frequency of his movements, together with the frequency of cardiac contractions, that makes it possible to draw the first conclusions about his viability and well-being. If the embryo is now without movement, the doctor will raise the issue of abortion. Still there are some weeks to wait and compare parameters on the following inspection, but it already alarming bells.

What is important to know the future mother

Ultrasound at 4, 5 weeks of pregnancy is not always done, but at this time, usually a woman already knows that she is pregnant. Therefore it is extremely important to know about the features of embryo development, as well as about the rules that a pregnant woman should adhere to. First of all, remember that the neural tube ends right now. Want your baby to be born healthy, calm and smiling? Then leave all worries and worries, and also drink any soothing herbal tea more often. Do not forget about the preparations of folic acid, which are extremely important for the proper development of the nervous system. In addition, this is the time when you need to carefully monitor your health. Admission of most drugs in this period is prohibited, and the most simple cold threatens serious pathologies of fetal development. It is for this reason that doctors try to dissuade you from doing the first photo of ultrasound. 5 weeks of pregnancy - this is the time when you need to first think about the health of the baby, despite the fact that the harm of this procedure is not proven, it is necessary to minimize all risks.

Opinion and feedback of expectant mothers

Usually this examination does not cause women special emotions. Ultrasound at the 5th obstetric week of pregnancy does not carry any information load. All that the doctor will see, while too much, you will not be able to find out about the future child's field, nor about how his development is going. However, if the doctor turns out to be a real expert, and also a kind and considerate person, he can tell you a lot about the features of embryo development at this stage, the milestones on which you need to pay attention. It is this examination that completely eliminates ectopic pregnancy and establishes that the fetus develops exactly where it should be. But take your time while making a photo. Ultrasound of 5 weeks of pregnancy shows very schematically, so it's unlikely that you will be pleased with the striped background with strange points in your family album. You will still have enough time and opportunity to capture the crumbs.

Is it harmful at this time?

In fact, with full confidence to you to this question no one will answer. Too many components. There is still no reliable data that would confirm that this procedure is harmful to the embryo. However, when talking about whether or not ultrasound is done at week 5, it should be noted that this procedure is not prescribed without serious reasons. These can be complaints of the patient herself (pain, discomfort, bleeding) or a doctor's suspicion. And to exclude the risk for the mother, the gynecologist can send to the ultrasound. Of course, in any paid clinic you will be given it even without a referral, especially if you say that you are going to a medical abortion.

However, in medical circles the question of whether ultrasound can cause harm to the fetus is periodically raised if this examination is performed in the first weeks of pregnancy. Meeting such information, future mothers themselves start to be wary of such a procedure, so if the doctor does not prescribe you a survey, it is better to abstain from it.

Determination of possible pathologies

Probably, all women are interested in the question, whether ultrasound will show any malformations of the baby at the 5th week of pregnancy. In fact, this is unlikely, and therefore it is believed that ultrasound procedure at this time is of little use. It's not even about the fact that it is harmful, which is not proved, namely, that it is not informative. That is, if a woman does not bother, then you can do without this procedure. But if already there are any failures and violations, the doctor will definitely propose to have an ultrasound examination as soon as possible.

We note at once that the anomalies of the structure of the embryo will not be seen, but it is quite possible to note such disorders as detachment of the fetal bladder or hypertension of the uterus. Of course, it is ultrasound that can determine the presence of an ectopic pregnancy.

If an ultrasound embryo is not detected

In fact, ultrasound 5-6 weeks of pregnancy can not show, but who will give a guarantee that the doctor was not mistaken with the term? If you have a period of only 2-3 weeks, then the doctor will not be able to accurately see the embryo inside the fetal egg. This can be a serious stress for a woman, especially if the doctor hurries to give direction to the termination of pregnancy, referring to the fact that the embryo stopped at an early stage. However, do not rush to panic, you have enough time to wait. After 10-15 days, repeat the procedure, if the results match, then you will have to make a decision. However, it must be remembered that this applies only to those women who feel well. If you are concerned about pain, then do not pull, it is better to trust the doctor. Women's health is a priority, because she can become a mother more than once.

Ultrasound in the following weeks

Perhaps this will convince you, but a different picture will be seen by the doctor, if you have 5 weeks, 5 days of pregnancy. Ultrasound can be more informative. At the sixth week the doctor should already accurately detect a fetal egg in the uterine cavity. The yolk sac is clearly defined in the fetal egg. The size of the embryo is already 6-19 mm, and before the work of its own internal organs, the tissues of the yolk sac fulfill all the metabolic functions. However, its size should not be about 6 mm. On the sixth week the doctor should already see a white ring, this is the future placenta.

In the seventh week, not only the presence of an embryo in the fetal egg is clearly diagnosed, but also the sensor records its cardiac contractions and motor activity. The size of the fetal egg is 19-27 mm. The heart rate is up to 150 beats per minute.

Important points

First of all, it should be noted that if the doctor assumes some kind of pathology, this is not yet a diagnosis, but only suspicion. Since it is considered the most uninformative ultrasound in the 5th week of pregnancy. What is visible to the doctor, we have already told you, but if the deadline is incorrect, then the conclusions will be unreliable. But even if the period is correct, individual developmental features may occur. That's why we say that all the once obtained ultrasound data are interpreted in favor of pregnancy and require mandatory confirmation in a few days. If a fetal egg is not found in the uterus, an ectopic pregnancy may be presumed. Suspicions of anembronia (empty fetal egg) may occur if a yolk sac is absent in a fetal egg more than 20 mm in size, if there is no embryo in the 25 mm egg fetus, or the size of the yolk sac is more than 8 mm. The doctor can also assume a frozen pregnancy if he can not determine the heartbeat in an embryo larger than 5 mm.

Alarm signals

Until now, we have talked about what a doctor can say on the results of ultrasound if the pregnancy is normal. However, in this case, for a period of 5 weeks, you can take your time not only for the examination, but even for the doctors. After all, registration is carried out not earlier than 10-12 weeks, that is, by the end of the first trimester. However, there are a number of signs that are evidence of a violation of the natural process of pregnancy. Normally at this time the woman should not feel her pregnancy, so if you have attacks of pain or discharge of a different nature - run to the doctor for the direction of ultrasound! Signs of miscarriage can be a thickening of one of the walls of the uterus. That is, excessive tension, hypertension of the uterine muscle threatens to expel the fetal egg. A timely study will help to conduct appropriate therapy and keep the pregnancy. The second sign may be a thickened myometrium. It changes the configuration of the fetal egg, and it will not escape the attention of the doctor who carries out the ultrasound. And, finally, the most formidable sign is the detection in the uterine cavity, next to the fetal egg, of some blood. Such clots are a sign of a threatening or already occurring miscarriage. The source of this blood is small vessels, destroyed by a fetal egg when inserted into the wall of the uterus. However, if the hematoma increases in size, it can put pressure on the fetal egg itself.

Thus, it can be said that ultrasound in the fifth week is not necessary. It should be done if there are some alarming signs that bother the doctor, in order to eliminate the risk to the life and health of the mother. If you are not worried about anything, then you can wait until the tenth to twelfth week, and then go through the first ultrasound and register. And most importantly, do not forget to eat fruit, drink vitamins and more to walk in the fresh air. Pregnancy is not a time for anxiety, so ask your family to shift all the worries to yourself for a while, but listen to beautiful music and talk with your child who will very soon learn to distinguish your voice from thousands of others.
