Sunbathing while pregnant?

FTM mom here! I’m currently 34 weeks pregnant. I’m off this week from work and have a pool to enjoy in the backyard. It’s around 80 to 90 degrees where I live, with some breezes throughout the day. I’m wondering if it’s okay to sunbathe? Of course if I feel hot I dip in the pool. I’ve been out for 3 hours and now I’m back inside. I got some color and a tiny bit burnt but am I fine? I want to enjoy the pool the rest of the summer but now I’m paranoid.😩😩😩
