Poop issues?

This is so embarrassing but anyone else have trouble being regular? I drink plenty of water. I can go sometimes & feel relief other times it's like seriously. I know I have to poop but why is it I can't!!! Ughh then I'll strain and get hemrroids. I'll be 30 weeks Saturday. Anyone else have this issue?!!! 😕🤔😩😩😩😩
