I've been taking Alysena 28 birth control pills for two months always consistent and at the same time or within the same hour everyday. Last month after my period ended I still had two days left of placebo pills and my boyfriend and I kind of had sex. What I mean by that is he wore a condom but he didn't go inside of me just around the opening of my vagina (as we are just starting with sex and taking it slow)he did not ejaculate but he did have pre-ejaculate inside the condom and the condom did not rip or break. My question is how likely is it that I could be pregnant from what I have described? Is it safe to have sex with a condom while on placebo pills? And how effective are condoms and birth control pills when having sex?
