How many hours after taking my seventh birth control pill will it be effective? its my first time starting birth control
A doctor has provided 1 answer
Basics: A primary effect of the pill is in keeping a hormone level up that prevents egg release.No egg=no pregnancy. Many companies suggest their pills are effective starting a week or 2 after they begin, but many OBGYN's recommend at least a month using backup BC until your body adjusts to the pill. If it matters, I would be cautious & use a backup BC.
