Birth control but no condom

Hey, I’m 18 and me and my boyfriend just had sex without a condom for the first time. I’m 100% sure that he didn’t cum in me because I saw him a while before he came- which was outside of me nowhere near my vagina. I have been on birth control for a little over two weeks now and every website I’ve seen says I’m protected if I’ve been on it for at least 7 days. My next period should be in around 10 days. Should I be overly concerned about being pregnant. I’ve already read that pre cum can get you pregnant but I’ve been on the pill for over two weeks and although I know the pill isn’t fireproof I just wanted to see what ya’ll thought I should do or if I should be worried (because I’m kind of a little nervous since it was our first time without a condom)! Thank you so much for any input.
