I'm on the pill and I take it around the same time (give or take 10mins) or at the same time every night(usually 10pm). My boyfriend and I are sexually active and we usually use a condom. On the 2nd of July the condom broke and he finished inside me. I had already taken my pill for that night before we had sex. The next night we were busy and I took my pill around 40mins late. I don't think that it should render the effectiveness of the pill. But I am on the 4th day of my placebo pill and I haven't gotten my period yet. Should I be worried?
