There is no pregnancy reaction after pregnancy, this situation belongs to the physiological manifestation. It is not possible to judge good or bad by this phenomenon. There are some pregnant women who are stronger and do not have pregnancy reactions, and as long as the fetus develops normally by ultrasound examination, it is a sign that everything is good. The fetus without pregnancy reaction and the fetus with pregnancy reaction are the same and there will not be any difference. During the period of no pregnancy reaction, as long as the ultrasound examination is normal, you can rest assured that the fetus will be well nourished. You can eat more nutritious food, more milk, lean meat, egg yolk, and more fresh fruits and vegetables, which will help the healthy growth and development of the fetus. You also need to pay attention to keep your mood relaxed, not too nervous, and try to exercise less in the first three months to avoid miscarriage.
