Once stopping Birth Control pill, because the hormons contained in the pill is withdrawing from your system, you will experience break through bleeding and erratic or irregular bleeding. You may also miss a period or several periods for the total amount of time the BCP is still in your system. BCP remains in your system for three full months before your body is completely rid of BCP.
