Medroxyprogesterone
"I got the shot Jan 2014. I bled every day for the first three shots - 9 months. I wasn't allowed to get off of it because my mom was in charge. After the third shot I haven't had a period or spotting since. I have gained a lot of weight, around 50 pounds to this day. I really believe it's because of the shot because my eating habits haven't changed and I work out more now than I did before. The shot doesn't hurt but it feels uncomfortable for about a day or two. I was considering switching to Nexplanon (the implant in your arm) but after reading those reviews I think I've decided to stay with the shot. I haven't gotten pregnant and I haven't had my period since the third shot. If I don't get the weight off soon I will switch."
