so much pain 😫

I'll be 31 weeks on Friday and I'm dying right now! Our little boy is moving so much and it literally feels like my hip bones are being seperated. And it keeps feeling like his head or hand or feet is popping out of my cervix! It hurts so bad but I can't tell if it's a Braxton Hick or real deal contraction or if I'm just being a whimp. I go into my doctors office on Thursday. Has anyone else dealt with this kind of pain from kicks and movement? Should I try calling the hospital? I'm probably just being a wuss but any feedback would be greatly appreciated!
