"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."
