Welcome to HealthcareMagic. If you stop getting Depo-Provera
injections, your period usually returns within 3 to 10 months but sometimes it may take 12-18 mths. I suggest that you consult your gynecologist and get yourself examined to rule out other causes of such symptoms like pregnancy
. Although rare to have pregnancy with Depo shots, but failure cases are not uncommon.
Please get an examination done from your gynecologist. Hope it helps you. Regards.
