Yes its normal im 23 weeks and iv noticed that iv gotten tighter and it hurts almost every time i have sex with my bf and we can only do missionary... but everyone is different
Yes it is super normal. You will just have to find a position that you can be comfy with. For like a month all I could do was missionary. But now I can do it all. But it will change sometimes I can't do certain positions for a few days then I can. Pregnancy is all trial and error in that department.
