So me and my boyfriend are in a long distance relationship (he lives a few hours away), and he finally got a few days to come visit me. We spent a few nights together. I am on the birth control patch. I change the patch every Tuesday 3 times a month and then I have a week without it that I’m supposed to get my period. however he didn’t pull out (sorry tmi) in time and came in me and so the next morning we went and bought the pill.. but I always get my period the Wednesday RIGHT after the Tuesday that I take the patch of for the week.. and it’s only been a day but it’s never been late like this and I’m slightly concerned and hoping that it’s only because of the plan b pill bc my boyfriend is scared and I’m only about to be 18 and I don’t want to be pregnant just yet. So maybe I’m just paranoid but does anyone know if the plan b pill can make your period late?
