This is a very important period of pregnancy, during which the fusion of parental cells occurs, the fertilized egg attaches to the uterine wall, and the development of the embryo begins. All tissues and organs are formed and they begin to perform their functions. The placenta and umbilical cord develop, which play a vital role in providing the baby with oxygen and nutrients.
This period is especially dangerous with regard to the effects of various unfavorable factors and toxic substances on the embryo. They can negatively affect the baby, which can lead to a frozen pregnancy, miscarriage, or the formation of various pathologies.
The size of the uterus gradually increases in the first trimester. Only towards the end of the first trimester does the uterus begin to emerge from the womb. The size of the baby at this stage does not exceed 8 cm, and its weight is approximately 20 g. However, some women claim that their belly has increased in the early stages of pregnancy. Yes, this happens, but not due to an enlarged uterus, but due to increased gas formation and bloating. Such processes are caused by ongoing hormonal changes in the body and are absolutely normal.
As a rule, in the first trimester, a woman registers for pregnancy with a gynecologist, takes the necessary tests, and undergoes a series of examinations. If bearing a child is not part of the couple’s plans, then for up to 12 full weeks the resulting pregnancy can be terminated at will.
In the early stages of pregnancy, you should be very attentive to your health, get enough sleep, walk a lot, don’t be nervous, eat right, and give up bad habits.
