Depo shot ...

So I had just no longer gotten on depo after the birth of my son, on the day of my discharge. It's going on 8 weeks now & I am still bleeding! Idk of this is a period, lochia or a side effect of depo but I am TIRED of it & I want it to stop! I have another doctors appt. scheduled to see why I'm still bleeding but for now, has anybody ever experienced this? And does it have to do with depo maybe?
