Help.

Okay. I am 33 weeks and 2 days. I am having so much pain on my, I guess you would call it, pubic bone. Mainly when I flip over or get up from laying down. It feels like it’s broken!! The triangular part of my vagina is what I’m talking about. It feels like there’s so much weight on it and I am miserable. I don’t even want to get up or even move. Does anyone know what this is? I have an appointment Wednesday and will for sure talk to my doctor but I would like to know I’m not the only one?
