Could be Braxton hicks, or just the pressure. I'm surprised you can lay on your stomach--my bump is still fairly small and I can't do it bc it's uncomfortable
Sounds like Braxton Hicks. Try changing position and propping yourself up more. If I lay flat on my side, I did to get them initially especially if baby is active, but it usually goes away within a minute or so. I get a ton of Braxton Hicks though triggered by all sorts of things...
This happens to me if I don't support my bump with a pillow or something. It seems like a combination of Braxton hicks contractions and round ligament pain.
