In general, lying on the right side in mid-pregnancy usually has no effect on the baby, and you can choose an appropriate position to rest under the guidance of your doctor.
During pregnancy, as the weeks of pregnancy increase and the uterus enlarges, the position of the pregnant woman will affect the blood pressure changes. In the middle and late pregnancy when lying down, the enlarged uterus will compress the inferior vena cava, so that the return blood volume and the volume of cardiac excretion will be reduced and postural hypotension will occur.
Therefore, in mid-pregnancy, pregnant women should be encouraged to rest on their side, either on the right side or on the left side, which usually has no effect on the baby.
