… At the clinic they told me one week, but online it said fourteen days.
If the Depo-Provera shot is given within seven days of your menstrual period, no back-up birth control is needed. If you were given the shot after the seventh day of your menstrual cycle, it is important to use a back-up method for seven days. Keep in mind that Depo-Provera does not prevent against sexually transmitted infections, so it’s important to use a condom consistently, correctly, and every time!
Although menstrual changes are very common for Depo patients, we do recommend taking a pregnancy test if you do not experience bleeding after your first month on the shot. Thanks for double-checking on the details—knowing how your birth control works best is very responsible!
