Depo-Provera
"I'm 18 and got this for heavy bleeding. I've always heard that bc makes you gain weight but was NOT expecting what I go. I gained 20 lbs. from just one shot. Sent from my usual 135 to 155. Made me nauseated after I ate anything. Had to buy a whole new wardrobe because I couldn't fit anything. And my sex drive! Omg I felt like a 90 yr old women because I was as dry as a desert and couldn't get wet no matter what. It was awful. I really really don't suggest this. I would much rather have cramps that make me throw up rather than take this shot ever again"
