Medroxyprogesterone
"I definitely regret take the depo shot as BC. I didn't spot the first time I got the shot but a month or two after I started spotting and it's been constant for about 6 months now. The main issue was that I gained weight on it. I have always been the same weight no matter how much I eat and don't exercise. This is the first time my weight has increased this fast and its quite depressing. I was supposed to go in for my fourth shot but decided against it and am going to be trying to patch now. Hopefully it doesn't have the same side affects. Not having a period with cramps every month was great but I'd rather deal with that than constant spotting."
