I don't have any personal experience about depo provera but I had a friend who is having the same experience that you are experiencing too. Actually, depo provera is a contraceptive injection that may cause a lot of serious complications. It's really not good to use this without having to consult a doctor. In your condition, that you experiencing heavy bleeding, I suggest that you need to stop using it, because it's not good and it's very risky on your part if you continue especially if your bleeding is without known reason.

I don't have any personal experience to share about depo provera, but since it's really not safe to use..then I think I will or don't have plans of using it too.

I'm afraid to use any kinds of birth control because of it's side effects. Most especially Depo-Provera.

If you think you are already experiencing abnormal bleeding upon using depo porvera, then better stop it..don't wait for more serious thing to happen before you will decide on stopping it.

if that's the case, then ask your obgyn about your concern. i don't think you should bleed that long, there must be a reason behind that.
