If your baby's head presses down on your pelvic bones a certain way during childbirth, it may create a gap between two bones at the front of your pelvis. These bones come together through connective tissue called ligaments. They often stretch more easily during pregnancy, and this can lead to pelvic girdle pain. Your doctor may call it a separated pubic symphysis. There may be swelling or bleeding when the ligament stretches and the bones come apart.
A gap between your pelvic bones can be painful. That pain can last for 3 to 8 months. It may hurt when you walk, and you may have trouble walking normally. You may also be in pain when you sit or stand for a long time.
