Sunbathing while pregnant?

witchy 🌙
I'm due in September, so I'll be pregnant all summer. It's already reaching the high 70s where I live. I go to the lake and on walks often when it's nice out like this, is it safe? Obviously I'd use sunscreen but is it safe to lay out in the sun? I only drink water so I drink A LOT of it. Probably a stupid question but I honestly want to know.
