The location of the pubic bone in pregnancy is usually the pubic bone, which is under the pubic hair covering the vulva and can be touched with the hand to the lower abdomen where it hardens. The pubic bone remains in place during pregnancy and non-pregnancy and is located at the junction of the thighs and lower abdomen. The pubic bone consists of the pubic symphysis and the pubic arch. If you feel downward from the abdomen, the part that becomes hard and soft is the upper edge of the pubic symphysis, which is labeled as the position of the pubic arch in obstetrics. The pubic bone is located in the anterior and inferior portion of the hip bone, and is divided into the body of the pubis, the suprapubic branch, and the infrapubic branch. The body of the pubis constitutes the anterior lower part of the medullary socket, which continues inwardly into the suprapubic branch, reaches the pubic tuberosity, and then continues outwardly into the infrapubic branch. The gradual increase of the fetus during pregnancy, the pressure of the uterus on the pubic bone area will be more and more, the blood circulation around the pubic bone will also be affected, which leads to the phenomenon of pubic bone pain in some pregnant women.
