I have never had unprotected sex before but it is something I would really like to try to be closer to my boyfriend. I know that the pill is 99.9% effective but we don't want to chance it so we use condoms. My question is if we wait until the day after my period to have unprotected sex while I'm on the pill regularly, is there a chance that I could get pregnant? Thank you for you responses and your time. :-D
