About 3 days: withdrawal bleeds are caused by the destabilization of the lining of the uterus when it is no longer exposed to the progesterone component of your birth control pill. restarting birth control pills after you have started bleeding can shorten your period but will not stop it instantly because the process has already started I would expect about three days.
