Hot tub sex?? Should I worry?

So I just recently lost my virginity to my boyfriend!

And the next night we had sex multiple times.. all with a condom except one time. That one time was in a hot tub. It honestly wasn’t planned. It just happened.

I’m on birth control but him and I are both freaking about because 1. We didn’t use a condom. 2. We were in a hot tub (possible infections and such)

Am I okay? Nothing seems off right now. But I over think everything!! Please leave your opinions or advice.
