Depo-Provera
"I'm not sure if I would recommend this birth control before others to someone else, but it worked great for me for seven plus years. Mind you, I was told by my endocrinologist that my GP should have never allowed me to stay on this bc because of the side effects of losing bone density mass - because of this I now have osteopenia at age 29. Why rate it an 8? Because other then this (which I am now "fixing" with weight lifting and calcium/mag supps) I never had any issues with the depo. I didn't have to remember a pill and had no side effects from it. Because of this, I would recommend it. I took it for convenience but my bone density suffered because of it."
