Help!!!

Sara • 1st baby. 💎 scared, but excited!!!😍
Idk if this is normal or not but I keep getting a really really bad pain on my side. Almost like my butt bone or something. I can't sit. Cant stand. And when I sit to go pee it feels like my leg is being ripped off and I can't move anywhere or it makes it so much worse !!! i vant even walk anymore ...What can I do??? Is this normal?!
