Medroxyprogesterone
"I was on the Depo Vera for 4 years. It prevents pregnancy and I didn't have to worry about taking any meds or what not. But if I didn't take the depo right when it was due I would spot like crazy. I decided to stop because it just wasn't normal. I stop taking the depo vera (Feb-16-2015) it is now (June-3-2015) I'm still bleeding. My sex life is a wreck me and my boyfriend just deal with it because I will not suffer because of this lol. My advice don't do it. It's horrible and it really messes up your mensual cycle."
