abnormal uterine bleeding
"Do not take this depo provera shot.  I have not stop bleeding and I  took one shot gained 4 pounds because of the shot so I have stopped taking it  and now  I'm bleeding and it won't stop. It's been going on for months now. I never had problems with my period until after I had the depo provera. Don't take the shot you will  not maybe ever to have kids again. Bleeding doesn't stop.   This shot should be discontinued and off the market."
