The midpoint of the upper edge of the pubic symphysis is roughly at the pubic hair of the lower abdomen. When you feel down from the lower abdomen near the pubic hair, you will come across a hard part which is the upper edge of the pubic symphysis. After pregnancy, due to hormonal effects, the joints and ligaments at the pubic symphysis tend to become loose, and pain symptoms will occur, which is a normal reaction to pregnancy. In the late stages of pregnancy, due to the growth of the fetus, the pelvis will be stretched wide, and the pain will be aggravated. After giving birth, you need to exercise properly, which can make the pubic symphysis slowly recover, if the recovery is not good, it is easy to have back pain, leg pain and other phenomena, and in serious cases, it is easy to have uterine prolapse, vaginal laxity and so on. After delivery, you need to get out of bed as soon as possible, and you can also use pelvic correction belt under the guidance of the doctor, which can promote the recovery of the pelvis and prevent post-partum discomfort, and it is also recommended to strengthen the diet and nutrition.
