I'm 11 weeks 1 days pregnant and Last night I was laying down on the couch and all of a sudden my rib area, and upper back area started hurting so bad it was very irritating when my fiancé tried to help and rub my back. I was laying on my side, so I rolled to my back and that didn't help at all. It has since gone away and I'm not having issues right now. But I definitely was hurting quite a bit last night. What could that have been?
