In my experience, deposit sucks. Just gonna be honest about that. I got my first shot on march 4th and have NOT stopped bleeding since then. It may just be me and my "organs" not wanting to cooperate, but I've gotten borderline anemic from bleeding so much and now I'm stuck taking horse pill prenatal vitamins. If you're going to go on deposit, it will probably take 2 or 3 shots in order to stop your period. I really hope it will stop mine soon because I dont know how much longer I can take this x_x make sure to get yourself a nice big bottle of vitamins with all the good stuff in it just in case you end up bleeding like I have. One of the side affects is weight gain, but I've lost 6 pounds in the past 2 months. Good luck! I hope you have a better experience than I have.
