i definately have a cousin whos like 20 or 21 with a baby less than 1 year old, who got pregnant while taking the pill every day. Definately not fool proof.
HOLD UP!! I noticed that some of the people on this board think it's pointless to pull out if the girl's on the pill. Well that is exactly why 2 of my best friends are about to become new daddies. Use common sense, NOTHING IS 100% FULL PROOF.
