Depo Shot

Brittney

I got my first depo shot on 1/8/21. According to my tracker I was supposed to start my period 10 days ago but im just having cramps and a lot of discharge but no period. I didn't have sex between my last period and the day I took the shot which is 2 days after it ended. But is it possible for the shot to stop your period after the first month? I was told 6 months to 1 year
