Im kinda anxious

So I’ve had sex for the first time like a week ago with my “boyfriend” and I felt completely comfortable with him and it was great for it to be my first time but we didn’t really expect for it to happen so we didn’t have a condom. Well I did but it was one that I found at an hotel were the usually leave condoms if your gonna have sex but that was last year during the summer. But we were both so heated that we used it. He checked the condom and it seemed fine but I’m just so scared that it wasn’t good and that I might have gotten pregnant. I’m about to get my period next week and I’m getting acne and my boobs are tender like they usually are when I’m about to get my period. Idk if I’m just being paranoid and freaking out for no reason or I should have something to worry about.
