So I found out I'm having a baby girl and this is my first baby. I thought by now that my stomach would be hard and not squishy. It's hard when I lay down and early in the morning when I have to go pee (tmi). I know she is moving I seen it on the ultrasound but I can't quite feel it either. Anyone else have this issue? I was 164lbs pre pregnancy and use to weigh 265lbs before I got to 164lbs.
