Pain in belly when sleeping on one side??

I’m 24+2 weeks pregnant and for the past few nights I find that sometimes I can’t sleep on either my left or right side because there’s a pain in my belly, where baby is, whenever I do. I can’t quite describe it but it’s almost like if I lie on one side I’m lying on the baby and squishing him and that’s why it hurts? 🤔

Has anyone else experienced this?

Also, the last 2 days he’s been moving a lot less than normal. I can still feel him move and kick me (he is right now lol) but he’s normally very active but he’s not so much at the moment. Should I be concerned? Or is it ok as long as I can still feel him? TIA
