Depo-Provera
"I've been on the shot for about 2 and a half years. The first few times I got the shot I had some inconsistent spotting. I could never tell when it would occur. After a while my body adjusted and I haven't bled since. Before I got in the shot I weighed about 98 pounds and now I'm at 110. THE SHOT DOES NOT MAKE YOU GAIN WEIGHT. The shot increases your appetite and it's what you eat and how much you eat that makes you gain weight. However no one informed me about the fact that it weakens your bones until about 1 month ago."
