My belly is hard on my side! Is anyone else at 34 weeks experiencing this?

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?
