Has anyone else experienced bad ab pain during their pregnancy? It feels like my belly is literally splitting open. It's like a tearing pain that goes in a straight line across the middle of my belly. It feels like it's on the surface, like my skin or ab muscles. There's no visible redness or irritation, so maybe it's just from the stretching. I'm 30 weeks and I'm hoping that it won't be like this for the next two months!
