It depends: It depends upon how consistently you are taking your birth control pills and how soon after sex you took Plan B. If you have been taking birth control pills daily at the same time without interruption you are 99% protected against pregnancy. Plan B is 95% effective against pregnancy if you take it within 24 hours of sex: 89% if taken within 72 hrs. Take Plan B only if missing birth control pills
