Okay, on this particular day, it was exactly two weeks after my last period, therefore i know there's a good chance i was ovulating. Anyway, i took a pill that day, except i was three days behind. I had sex that night without any other protection. Well, this is really irresponsible, but i stopped taking the birth controls because I didn't want to take the chance of me being pregnant and harming anything... Well, two days after i stopped taking the birth control i had sex again without any protection. I know there's a chance, but i was thinking if i had a pill in my system the day i had sex when i was ovulating, maybe an egg wasn't released? Or maybe it doesn't matter because i was behind on them. Could someone explain? WAS i protected that day i first had sex or wasn't i because i was behind?
