I took the pill the day after my ovulation day because on my ovulation day I was doing sexual stuff with my boyfriend (we did not have sex) but some of his ejaculation still fell very near my vagina (approximately around the outer labia). Would the pill I took (Postinor 1) still be able to prevent pregnancy even if taken the day after ovulation? What are the chances of pregnancy in the situation described, taking into consideration that I took the pill?
