I'm 36 weeks, starting last night the top of my stomach gets pretty painfull, my whole stomach gets very hard and lasts 5-10 minutes. I thought i ate too much at dinner, chinesse buffet. It stopped last night after I took a shower/rested and drank water. It started again this morning. I'm trying to drink water, take breaks often (attempting to clean and organize). I was wonder if it was bh, but thought bh only lasted 20-30 seconds? Baby seems lower to me this week than she fid last week. So, I dunno.
