Due to the cushioning effect of amniotic fluid in the uterus, pregnant women will not press on the fetus as long as they maintain a comfortable sleeping position. However, in order to promote the health of the fetus, try to choose the left side of the bed in the late stage of pregnancy. The fetus is protected by the amniotic fluid in the uterus, which has a certain cushioning effect. Normal sleeping positions of pregnant women will not press on the fetus, such as lying on the side, lying down and other sleeping positions. Although pregnant women do not directly press on the fetus, as the fetus grows, the uterus gradually becomes larger and may cause pressure on the blood vessels in the abdomen. The uterus usually belongs to the state of right rotation, which suggests that women in late pregnancy try to take the left side lying position, which is more conducive to the health of the fetus. Pregnant women should actively observe the fetal movement to determine whether it is healthy or not, and if any abnormalities occur, they need to go to the hospital in time, and under the guidance of the doctor to carry out standardized treatment, in order to promote the healthy development of the fetus.
