Depo-Provera
"While on the depo I had no issues other than severe weight gain. They tried to tell me that I was eating more and that's what caused it, but I was very strict about what I ate so I know without a doubt it wasn't that. Once I stopped the depo, about 2 months after I stopped the shots, I started cycling. My cycle was heavy and painful, and it hasn't stopped nearly 2.5 years later (I very rarely get a day or two where it isn't bleeding). I'm still in the process of getting lab work done and finding a resolution. 



Depo seems to work wonderfully for some people, but it works terribly for others. I'm not sure if there's a way to screen if it will work well with your body or not, but because of this I wouldn't recommend it."
