I’m on the pill and I take it continuously and get my period every 3 months. I’m now ending my third pack and I started bleeding yesterday, but it quit because I hadn’t quite gotten to the end of my pack (I just took my last pill today). I had unprotected sex today and I am debating whether or not I should buy a plan b (bc I sometimes take my pill late) or if I could/should just wait to start my period. Which is a better option? If I don’t take a plan b how likely is it that I could get pregnant?
