In the third week of gestation, the development of an immunosuppressive protein occurs, which is called the first sign of pregnancy. Without it, the human body could confuse the embryo with a foreign body and reject it. Even a small amount of this protein will be enough for the test to confirm pregnancy.
During this period, the embryo is still not at all like a child. Outwardly, it is rather an accumulation of cells that can only be seen with a powerful microscope. However, the embryo already has genes that can be used to determine its growth, gender, external characteristics, as well as individual characteristics of the child. Even despite the fact that in the first weeks of pregnancy the human embryo is practically no different from the embryo of any animal, by the end of the first trimester it will be possible to accurately determine its legs, arms, head. In the third week, the laying of all internal organs begins. The first to form the heart, genitals and neural tube. On the twenty-first day of bearing a child with ultrasound, you can already fix the heartbeat of the embryo.

Some expectant mothers have hypersensitivity, a change in appetite, rapid fatigue or pain in the chest area. During this period, many women become quick-tempered, irritable and tearful.
