Started birth control (microgestin) on 2nd day of period, how long till it is effective in preventing pregnancy?
A doctor has provided 1 answer
This month: As long as you take the pill everyday as directed at the same time each day, the pill is effective this month. Some exercise caution by using a "back up" method of contraception for the first month in conjunction with the pill.
