However, after late pregnancy, the uterus will compress the inferior vena cava and cause hypotension, so it is recommended to lie on the side, especially the left side of the best position. After pregnancy, you should have a reasonable and balanced diet under the guidance of your doctor to ensure that you consume sufficient nutrition to meet the needs of the mother and fetus. In early pregnancy, you should pay attention to proper rest, avoid exertion and strenuous exercise, and prohibit coitus. In the late stages of pregnancy, you should follow the doctor’s instructions to take obstetrical examination on time, and strictly count the fetal movement to evaluate the intrauterine state, and go to the hospital in time when there is a decrease in fetal movement.
