My boyfriend and I had sex just over 2 weeks ago. It was my first time and we had unprotected sex. I was taking the pill (Ginette 35) everyday without fail, except on the day that we had sex however, I did take the pill that I was meant to take around 9 hours after (that same day that we had sex). My boyfriend did not ejaculate inside me, but I'm so afraid that there is a possibility that I could have fallen pregnant from pre-ejaculation. We did struggle to get my boyfriend to have an erection, and he claims that he was not fulyl erected when we had sex. My period is expected this week, and I stopped taking the pill 4 days ago as I have reached the end of my 6 month course, however my period is delayed. I have been feeling so stressed out and not sure if that is the reason for the delay. Can you please offer me some advice on the matter?
