Oral Contraceptives huh?? They didn't make me b%$^%* until I realized I was PREGNANT with DS...LOL Guess it was truely meant to be...
Those who get pregnant "on the pill" are usually making mistakes like forgetting a day, not taking them at the same time of day every day, or taking a concurrent medicine that decreases the effectiveness of the Pill.
There is a slim, very slim chance of getting pg on the Pill even though you do everything right, but since its so slim, I question anyone who claims they got "pg on the Pill"!
