I take the pill everyday, but two days ago I took the pill about 4 hours late due to the fact it was not on me at the time and where I was at. I had unprotected sex the day before in the shower, but he did not ejaculate but instead pulled out before doing so. I know I shouldn't worry because I know a lot about this but I just want to not have any doubt in my head as I'm a worrier. Should I worry???
