sharp pain in vag.

Is it normal to get a sharp pain inside your vagina during sex? I'm going to the docs tommorrow for my 33 week appointment and I'm going to ask, but it doesn't happen all the time. I want to say its my cervix but I'm not sure.

normal. as long as you arent bleeding or dubbled over in pain. you cant feel your cervix dialating. more growing pains is whtat i was told.
