Some women are already fully experiencing morning sickness, others are beginning to perceive subtle symptoms, and there are also those who do not yet know they are pregnant. However, the 4th week from conception and 6 weeks from the last period means that bigger and bigger "miracles" are happening in a woman's body. The development of the embryo (baby) progresses and the foundations for the development of all the organs, systems and connections begin to form so that the nascent life can begin to function. It is during this period that you should inform your gynecologist about a possible pregnancy, and if you are lucky enough to have a free appointment, you will also have your first medical examination.

The woman is currently in the middle of the 2nd month of her pregnancy. The way to the desired baby in your arms is still quite long. The baby has already developed a simple heart that powers the circulatory system, and during an ultrasonographic examination you may even hear the heartbeat. The beginnings of pregnancy are very important, because a number of processes take place in a woman's body, which decide whether the pregnancy will be sustained. The symptoms of pregnancy are starting to become more pronounced in many women. However, it is also necessary to monitor possible complications. How does pregnancy develop in the 6th week?

6th week of pregnancy – baby's development and heartbeat

The embryo is currently around 3 to 6 mm in size. This is the equivalent of a grain of rice or lentils. From about the middle of the 6th week, it is possible to measure CRL values, although the shape of the embryo still does not resemble the human body. Some doctors record CRL values as early as the 8th tt. The fetus grows faster from week to week and the foundations for all important organs and systems in the body are formed. From a visual point of view, the head of the embryo develops the most, which has visible sockets for the ears, eyes and nose. In the lower part there is a so-called the tail, from which the spine will be formed.

The neural tube should close during this week so that the spinal cord and brain can develop. The basics of the locomotor system are also developing. Limbs begin to take shape very slowly this week. The same goes for some bones. The body of the embryo is already covered by a very thin skin. The sonographer in this phase can see only a small yolk sac in which the embryo flickers. During the examination, you may hear a surprising sound, which may be a heartbeat. It is still not a typical heart, but just a simple micro-heart, which has a beating frequency of approximately 110 to 150 beats per minute. It is also important that the umbilical cord connects to the placenta so that oxygenation and nutrition of the fetus can take place. For now, the circulatory system is connected to the chorionic villi on the wall of the uterus.

Other important bodies are also beginning to form. Kidneys, liver or lungs. The chest and ribs also begin to develop. This is a clear signal of the beginnings of the urinary, reproductive and digestive systems. During this period, the fetus is extremely susceptible to developing defects or genetic mutations. Therefore, it is important for a pregnant woman to avoid all harmful factors from alcohol and smoking to excessive stress.

What is CRL and how does it relate to baby development? You will also find this information in your pregnancy book, which you will receive after your first visit to the doctor. CRL is an abbreviation of the English words crown - rump - length. It is a measurement of the dimensions of the fetus from the top of the baby's head to the coccyx. This parameter is given in millimeters and is determined by the doctor regularly during every ultrasound examination until approximately the 20th-21st week of pregnancy. The CRL standards (embryo-fetal dimensions) are set for individual weeks, but these are indicative values, so there is no reason to panic if there are deviations. A difference of even two weeks is taken into account. This measurement is decisive from the point of view of determining the expected date of birth, possible problems in the growth of the fetus are detected, and also, if the woman is expecting more children, it can be observed whether the fetuses are developing at the same time.

First sono and visit to the gynecologist

From the 6th week of pregnancy, the topic is an examination at your gynecologist. If you have a pregnancy confirmed by a pregnancy test (note at least two positive pregnancy tests) and you have good reason to believe that you may be pregnant, book an appointment with your doctor. Most women visit a gynecologist around the 6th to 10th week of pregnancy. So don't worry if you can't get to the doctor in the 6th trimester. The exception is if you suspect certain complications.

When visiting a gynecologist, a group of examinations awaits you. The basis is the confirmation of pregnancy. In the 6th week of pregnancy, the doctor performs an ultrasonographic examination, which confirms so far only a biochemical pregnancy, which at this point becomes clinical. In early pregnancy, a vaginal probe through the vagina (vaginal ultrasound) is used to monitor the fetus. It is important that the embryo is implanted in the uterus and not in the fallopian tube or in another inappropriate space. This would be an ectopic pregnancy, which is unsustainable. It is also determined whether it is a multiple pregnancy. From this moment on, you will keep a pregnancy book. Furthermore, during the interview, the doctor will be interested in when you had your last period and approximately when fertilization occurred. The doctor will determine the date of birth, which will be specified in the following weeks.

The doctor will also be interested in your family history and your current state of health. The gynecologist will ask about what diseases you have overcome so far, what medicines you take, whether you have allergies or other health complications. Also what pregnancy symptoms you are experiencing. Complete laboratory tests, blood and urine sampling will be performed. A complete blood analysis is performed to determine the blood type and Rh factor (+/-), but also to detect the presence of various antibodies in the blood against certain diseases (syphilis, HIV, toxoplasmosis, rubella, chlamydia, jaundice or inflammatory diseases). The level of hormones in the blood is also investigated. They will measure your blood pressure and your height and weight. Any further examinations by a dentist, neurologist, internist or other specialist are determined by the gynecologist. At the same time, your doctor will arrange further meetings and examinations with you.

How to calculate the due date? It is important to say that the due date itself represents an indicative figure. You can calculate it simply by subtracting 3 months from the first day of your last period. You add 7 days to this number (the calculation applies to a 28-day cycle). Online calculators are also available for calculating the due date. However, your doctor will most accurately determine the date of your birth.

Women in the 6th week of pregnancy may experience discharge, spotting, or light bleeding. This is a normal phenomenon. The tissues of the uterus get blood, and occasional traces of blood do not mean any problem. The same applies to occasional pains in the lower abdomen. The reason is the stretching of the uterus and its growth. The tissues are stretched and cause occasional spasms. However, if the bleeding is more intense, lasts more than two days and is accompanied by strong cramps, increased temperature or diarrhea, visit your doctor immediately.

One of the discussants also dealt with the case that the doctor did not see an embryo in the uterus in the 6th trimester and the cavity (gestational sac) of the uterus was empty. The reason, according to the experience of other mothers, is that the fetus is still too small and cannot be identified by ultrasound. Therefore, it is recommended that potentially pregnant women wait for the first examination at least until the 8th trimester. A rising hCG value can also confirm pregnancy. At 6 weeks of pregnancy, it is already at the level of 1,080-56,500 mIU/ml.
