Do they do an ultrasound at 2-3 weeks of pregnancy?

Although being pregnant is an exciting journey, there are a lot of questions and concerns that come with it, especially in the beginning. One frequently asked question by pregnant women is if an ultrasound can be performed as early as two or three weeks into the pregnancy. Since there is often uncertainty during this time, women may be anxious to find out if they are pregnant as soon as possible.

The body is only starting to change at this early stage, so even though a positive pregnancy test might suggest that you are pregnant, it’s still unclear if an ultrasound can find anything. It’s normal to question what can be seen and if an ultrasound is really necessary at this particular moment.

In this post, we’ll discuss whether an ultrasound is normally done between weeks two and three of pregnancy, what medical professionals typically advise, and what other techniques are frequently employed to confirm pregnancy at an early stage.

When is it done?

The majority of the time, an ultrasound is only done between weeks 10 and 12. This period was not chosen at random by the doctors. Early embryonic development exposure to ultrasonography is thought to have a number of negative effects. The development of different intrauterine developmental disorders is the most dangerous of them.

Doctors use a special term called the "obstetric period" to assess the gestational age.

Commencing on the first day of the final menstrual cycle, it is measured. Doctors who perform ultrasound diagnostics typically use the gestational period, which is very different from this period. This will obviously be a shorter period than the obstetric period.

It should be noted that at present the situation with determining the gestational age has improved significantly. Modern ultrasound machines used in work immediately establish the obstetric period of pregnancy. This is determined by entering the initial parameters that the doctor specifies before conducting the study. In this case, in the conclusion after the test, the doctor already specifies the obstetric period of pregnancy. This is much more convenient, especially for obstetricians and gynecologists in their work. In order for expectant mothers not to get confused with the use of these concepts, they should use the obstetric period of pregnancy. This will allow pregnant women to speak the same language with their obstetricians and gynecologists.

Ultrasound at 2-3 weeks is carried out in most cases to exclude or confirm the fact of pregnancy. However, this type of examination is not the "gold" standard for this. Pregnancy in a woman"s body at this stage is confirmed by a clinical examination conducted by a gynecologist, as well as a special biochemical marker – hCG. An increase in the blood of this hormone in most cases indicates the possible emergence of a new life in the female body. Ultrasound examination, carried out on a woman who has a delay in her next menstruation, quite often reveals not pregnancy, but various pathologies. As a rule, the development of this situation is caused by the patient"s polycystic disease or cystic formations of the ovaries. Hormonally active neoplasms in this case lead to an imbalance of female sex hormones, which ultimately contributes to a delay in menstruation.

How it is carried out?

Doctors use specialized sensors to carry out the study. There are two ways to perform ultrasounds: transvaginally and transdominally. There are specific indications and contraindications for each of them. Using these techniques, you can determine the expectant mother’s uterus and other reproductive organ appearance.

A gynecologist determines which approach is most appropriate for a given circumstance.

Sometimes the anticipated conception date is set incorrectly. In this case, an ultrasound examination reveals that the child is two weeks older than anticipated by the doctors. Experts can also conclude that the fetus is developing two weeks behind schedule. Doctors in such cases order a follow-up exam, which is performed a few days later.

Doctors utilize specialized sensors to perform the examination. The examination is done through the abdomen’s skin when using the transabdominal approach. The vagina is penetrated by a transvaginal sensor. Many medical professionals think that this early-pregnancy examination method provides more information. The ultrasonography allows the physician to take images. They are documented in the medical file. These photos are taken when a woman exhibits any abnormalities or diseases. An ultrasonography specialist can repeat such a picture with multiple examinations. This is required to monitor the dynamics of this pathological condition’s development.

It’s usually too early to use an ultrasound to find anything significant at 2-3 weeks of pregnancy. The embryo is still too small to be seen, which is why most doctors advise waiting until the embryo is at least 5–6 weeks old, when the heartbeat is typically visible. Rather than using an ultrasound at this very early stage, blood tests are frequently used to confirm pregnancy.

What can be determined at this time?

Ultrasound performed early after conception can only show the presence of an egg that remains in the uterine cavity. This is the time when a small fertilized egg can leave the reproductive organ along with the bloodstream. In this case, a woman may not even understand that she was "pregnant" for a couple of weeks. A delay in menstruation after unprotected intercourse is perceived by her, as a rule, as a hormonal imbalance. Obstetricians say that at 3 weeks pregnancy has not yet actually occurred. At this time, the risk that the fertilized egg will leave the uterus is quite high. However, it is worth noting that she already has a double set of chromosomes, received during conception from the future father and mother. During this period, the fertilized egg develops quite quickly. The cells that form it rapidly divide and differentiate.

According to medical professionals, a fertilized egg already has 32 tiny cells in the first week following conception. It already has more than 260 cells by the end of the third week. In the future, the first trimester of pregnancy will be a time of active growth.

The most critical and intense phase of such development occurs in the initial weeks.

During the twentieth day after conception, significant things start to happen. The implantation of the fertilized egg straight into the uterine wall is the most crucial of them all. At this point, a pregnant woman starts to exhibit typical behavioral changes and general health issues because she still doesn’t know about her new status. She might become allergic to specific scents, experience mood swings, and experience an increase in appetite.

By the time the dividing zygote attaches to the inner lining of the uterus, it is less than 0.3 mm in size. Such a tiny "formation" in most cases is not visible during an ultrasound. Later, as the embryo develops and grows, it can already be seen in the uterine cavity during an ultrasound examination. Usually, obstetricians-gynecologists prescribe an ultrasound at 2-3 weeks from the moment of conception for medical reasons. It is prescribed to exclude concomitant diseases of the internal genital organs, that the mother has and can aggravate the course of pregnancy in the future. Also, an ultrasound at this time can be performed in order to assess the effectiveness of in vitro fertilization after embryo transfer.

There are cases when doctors prescribe an ultrasound examination at 2-3 weeks after conception in order to confirm the fact of pregnancy. It is worth saying right away that such an examination is not always indicated. In practice, there are a huge number of cases of false diagnosis. In this case, a repeat ultrasound scan will be indicated in 1-2 weeks. Frequent ultrasound examination, especially conducted in the early stages of intrauterine development of the fetus, can lead to the development of the most unfavorable consequences in the future. The main feature by which the doctors of ultrasonic diagnosis are oriented is Hyperplasia of endometrium. This fact is an indirect sign of pregnancy. However, hyperplasia (an increase in the volume) of the internal lining of the uterus may also be a result of some diseases of this childbearing organ.

Skilled ultrasonographers detect a tiny indentation on the mucous membrane where the baby will eventually be.

They measure the initial thickness of the endometrium to ascertain it. Experts can also determine the uterus’s size and tone during the examination. Hypertonicity in a pregnant woman is a highly undesirable symptom, particularly in the early stages of pregnancy. Hypertonicity may occasionally result in spontaneous abortion or miscarriage. Additionally, the ultrasonography physician must assess the corpus luteum as part of the examination. Pregnancy’s active vascularization, or blood supply, takes place in the early stages. More dilatation occurs in the blood vessels supplying the corpus luteum. They also have a marked increase in blood flow rate.

This feature in the corpus luteum is due to the fact that it plays a very important role during pregnancy. It is this anatomical formation that doctors call the "baby bed". From it, the main fetal structures will be formed in the future, which protect the body of the future baby from the effects of external factors. Also, the corpus luteum has a pronounced hormonal effect. Progesterone synthesized under its active influence has a preparatory effect on the endometrium so that the implantation of the embryo to the inner wall of the uterus occurs. To assess the blood flow of the corpus luteum, ultrasound diagnostic doctors use special type of scanning – duplex. It allows you to assess the level of blood flow in any anatomical areas. A decrease in this indicator may indicate a violation of the course of pregnancy. In such a situation, doctors decide on the need to prescribe corrective drug therapy.

An ultrasound is typically not performed between 2-3 weeks of pregnancy because it is too early to find many changes. The pregnancy is still in its very early stages at this point, and the embryo is frequently too small to see on the scan.

Usually, doctors advise against getting an ultrasound until at least the fifth or sixth week of pregnancy. By then, it will be simpler to verify the pregnancy and detect the first indications of the developing child, like the heartbeat or gestational sac.

It is best to speak with your healthcare provider if you have any questions about getting an ultrasound during this early stage. Depending on your particular needs and state of health, they will be able to advise you on the best time for an ultrasound.
