Pain behind belly button

Nicole • Wifey 4•16•16 ❤KGA❤ MC on 11•27•16 Pregnant with my rainbow 🌈 due 12/12

5w3d Rainbow baby. I think it's gas cramps but some pressure and pinching pain behind my belly button and down into my pelvic. Feel very gassy and feel the need to go to the bathroom but can't.

I've read a lot of it is normal but every twinge makes me nervous after my mc. Have my first appointment next Friday.
