What could this be?

Kristen

6am in my area and a huge thunderstorm is rolling in. As SO was getting ready for work I decided to go lay back down with our little girl (2yrs) and snuggle up. When I laid down she needed adjusted in the bed, so I scooped her up, sort of, and lifted her just enough to scoot her over several inches. When I did, I felt the most horrible pain in my lower cervix? It was almost a pop! but wasn’t, if that make sense. It was extremely painful though. The pain made me kind of “push” outward and the pain was intense. I laid there for a second like omg, and eventually got up to go pee and check to make sure there was no blood or anything of that sort. Normal pee, no blood, etc.. What on earth could that have been? Still hurting somewhat, but mostly my stomach now, like the bottom right side of my abdomen.
