Help!

Okay guys so I lost my virginity and I’m 17 a few days ago. Ivebeen waiting to lose my virginity till I got a serious boyfriend who loves me. But then I said that’s never gonna happen to I slept w the most random guy. So at first I sucked his dick a lil bit then his dick wasn’t going in and I was on top. Then he put me in this position we were going for like a minute maybe and then it slipped out and I was like damn hold on and he was like yeah I’m gonna go grab a towel and he came back and threw towel on the floor and asked if I wanted him to stick is back into me and I was like hold on I need a minute and we laid down and he was like damn that got me tired. So you guys think he came into me ?? I’m scared bcuz I haven’t been on birth control for like a month and he didn’t use a condom and started ovulating yesterday and I had sex 4 days ago. So I’m fertile rn not to mention my family is sooooooooo fertile its crazy. Give me advice y’all 😣
