If my boyfriend wore a condom the whole time and pulled out before finishing and we had sex on the last day of my period, what are my chances of pregnancy? I should also mention that I’m on the pill and I take it perfectly every day but since I was on my placebo pills I wasn’t totally sure how protected I actually am. I don’t think the condom broke or leaked any but I know that there is still a 2% chance of pregnancy even if the condom was used perfectly.
