Severe hip and abdominal pain at 30 weeks pregnant?

I've been having some pretty awful hip pain lately. I've also been having these sharp, pulled muscle type pains deep inside (if I had to describe where, I would have to say in the same area as my cervix).

Did anyone else experience this? This is my second pregnancy, my daugther was delivered by c-section about 15 months ago. Could it be c-section related? I am overweight, I know that could contribute to the hip pain, but these inner muscle pains are completely new and weird to me.

I have a doctor's appointment tomorrow (well, today now), but I'm hoping someone here can give me an idea of what the pain is from or what the doctor can actually do about it (has anyone been given something stronger than tylenol for pain during pregnancy?).
