Sleeping is uncomfortable

A mother

My belly feels painful when I’m sleeping, I’d wake up at least twice during the night to try to adjust into a better position.

I tried pillows between my legs, a huge pillow for support, my husbands thighs for support.. and much more 😂

The moment I get up off bed I feel completely fine, but why is laying down very uncomfortable all of a sudden and what could I do to feel better?

Anyone going through this too?
