So I've been taking birth control contraceptives (ORTHO-CEPT) but have missed the pills a couple days or so (not consecutively) but take the missed pill the next day. I haven't had sex for about 3.5 months but had unprotected sex yesterday, my boyfriend didn't pull out fast enough and came in me a bit. I'm debating on whether or not I should take the PLAN B pill. Also what are my chances of getting pregnant?
