In late pregnancy, it is better for a pregnant woman to lie on her left side. The reason is that during pregnancy, the uterus is usually in a right-handed position, and when lying down, the uterus will compress the arteries due to its enlargement, which will easily lead to the syndrome of supine position in pregnant women. If the left side is lying, it is better for the blood supply to the placenta, and it can also improve some uncomfortable symptoms caused by the right rotation of the uterus. Therefore, in most cases, it is recommended that pregnant women choose the left-sided or side-lying position in late pregnancy, and try to avoid lying down. In addition, it is important to pay more attention to the baby’s fetal movement during pregnancy. Fetal movement is an important indicator of how well the baby is developing inside the mother’s body and whether it is alive or not. If there is any abnormal fetal movement, you should come to the hospital at any time.
