I’m on birth control, which I take every single night, but last week I happened to miss just 1 birth control pill the night after I had unprotected sex. (I took the pill that night, I missed the night after). The next night when I remembered I took both pills and have been taking them regularly since. The one I happened to forget was the one right before the placebo week though. My boyfriend didn’t finish in me that night but it was without any other form of contraception. For the last couple months I’ve been getting my period on the Thursday of the placebo week, but I haven’t gotten it yet today. Could this be because of the pill I missed and it’s delayed? Or should I be worried?
