i’ve been on combination pill birth control for over a year. this month i took a few pills kinda late but always took them. last friday i had an unexpected (but great) hook up. we did not use a condom (don’t need a lecture i know him very well and feel comfortable) and he DID NOT cum inside of me. the night after i threw up after a night of drinking, and i had taken my pill not too long before meaning it was probably not absorbed in my body. that was my last active pill and i am now on my placebo week. does throwing up that pill give me a higher chance of getting pregnant? also, what are the chances of getting pregnant from precum on birth control a week before period?
