I wasn't sure how to name the title because I've looked all over google and no matter how I word it, it fails. Anyways; just above my pubic hair line, my waist starts to puff out and when pressed on it's hard. The area used to be flat but is slowly getting more and more rounded out. I run my finger from my one hip to the other and it feels like a bridge. Flat on each side but then raises in the middle. ((sorry, I'm sure you guys know that one lol)). 7-9 months pregnant. Is this my uterus? Thanks guys.
