Birth control

I started Birth control on February 1st and just last Friday i slept over at my boyfriend's house and we both decided since I'd been taking it for almost 2 weeks that he could cum in me, we had sex the whole weekend and he came in me each time do you think I should be okay on the birth control even though it was pretty early? I was also on my period, which i didn't expect because i started the pill a couple days before i was supposed to start (I've never been on birth control before, so i didnt think that I'd get it), so i was kind of worried but i also dont think i should be. What does everyone else think, should it be okay?
