Sex after period

So I’ve been taking birth control for 9 months straight, and my last day on my period was yesterday, (I take the bc with the 7-day placebo pills, and my period lasted only 5 days) like 12 hours since I stopped bleeding completely, and my boyfriend and I just had sex and he came in me and I didn’t take my pill until an hour or less before we did it. I’m kind of scared now. Or should I not be? Am I still protected? Should I take another pill just in case? What should I do. 😅
