Girls, anyone had this. I'll try to describe it (I'm going to see a doctor). 40 weeks already It starts shooting in the crotch, and it hurts so much. It feels like I can actually feel as if a bone shifts. Sharp pain and everything goes away. (It happens when it also sends to the lower back and the abdomen becomes less painful) Is this because of the pelvic bones?
