what is this!?

So what started as pelvic pressure (no other symptoms) has turned into a very painful problem. It is a pain radiating all the way from my lady bits to my rear. When I walk it gets so much worse. It hurts to lift my legs to lay down and really any movement. Has anyone had this? What could it be!? I called my doc over the pressure and they said if I'm not leaking amniotic fluid or bleeding and he's moving then it's probably his position, but I feel like after a week and it getting so painful maybe it's something else!? Anyone?
