Stomach very hard😫

Kayley • 24 years old, I have a little boy who’s 4 and I’m TTC my second baby!! 👶🏻
I'm 34 weeks tomorrow and most of the day my belly is like brick hard. It feels like my baby has no room when he moves, it's also very uncomfortable, it doesn't feel like a stomach it feels like i have a large rock under my top, is it normal to have a hard stomach at 34 weeks?
