If a pregnant woman puts her legs on the wall in early pregnancy, it will squeeze the pelvis and squeeze the uterus, and if it squeezes the abdomen in the middle or late pregnancy, it will also squeeze the uterus and reduce the local blood circulation, and it will cause the uterus to contract under the stimulation of external forces and cause the possibility of pre-miscarriage, inevitable miscarriage or premature birth. So don’t stand your legs on the wall during the whole pregnancy, it is very dangerous. During pregnancy you can go to do some yoga for pregnant women to facilitate the process of delivery in the future, it is still very desirable to do yoga under professional guidance.
