My belly is hard on my side! Is anyone else at 34 weeks experiencing this? Girls, if I lie down or sleep on my side, my belly is always hard (I turn over onto my back and understand that it's square in a minute, soft. For the last week. Although before it was all the same but just reversed. On my back, I couldn't lie down, and on my side, it was soft. But I can't sleep on my back and he's hard. I don't feel any pain specifically, but maybe after some time something somewhere might get slightly sick, I immediately turn over onto my back. How many times have I asked, nobody has experienced this?
