How soon does the combination birth control pill prevent pregnancy? it was started mid cycle. planned parenthood says 7 days.

A doctor has provided 1 answer

Birth Control Pills: I would never want to contradict Planned Parenthood. However, if my daughter was taking the pill she would be directed to use another form of birth control such as a condom until she had completed one pack of pills. In otherwords, to be safe I feel it is not completely effective until you have been on them a month.
