Avoid lying on your back after about the 4th month of pregnancy; doing so puts the full weight of your uterus on the inferior vena cava, or IVC, which brings blood back to the heart. As a result, this posture reduces the flow of blood to the heart - and to the uterus and baby. Lie on your side instead.
