Two months of having a consistent period doesn't seem normal. I know depoprovera causes irregular bleeding. Can I stop this? I have had enough!

Maybe. When you take depo provers, even though the medicine is supposed to work for only 3 months, it can affect your periods for up to 9-12 months after each shot. And often it can cause constant or very irregular bleeding. So you would need to consult a specialist to make sure nothing else is causing the bleeding and to try to help control things until the effects of depo are gone!
