Medroxyprogesterone
"I was on the shot for 2 years and 6 months. My first 6 months on the shot I bleed lightly but nonstop. After that I did not have a period for the 2 years. I gained 40  pounds and experienced major emotional side effects. I did not get pregnant on the shot because mainly my sex drive is nonexistant and I am so tired all the time. I have also believed this shot has messed with my blood sugar and blood pressure. I am ending my shot because of all the side effects."
