But how many days after Provera will your period start? When using Provera for amenorrhea (absence of menstrual periods) or abnormal vaginal bleeding, the medication is taken for 5 to 10 days. Menstrual-like vaginal bleeding usually occurs three to seven days after treatment ends.
Most women who take Provera get their periods within a few days of stopping the pill (itâs taken every day for five to 10 days, depending on your doctorâs preferences). 1  Itâs not unusual, though, to begin bleeding before you finish the course of pills or not until two weeks after you finished the pills.
