abnormal uterine bleeding
"I've been on the depo for over two years now. For the first 9 months I experienced light bleeding/spotting but the doctors told me to continue as it won't be long until my body got used to it. After my third shot the bleeding just stopped completely. It is best to carry on with it because I haven't had a period in over a year, just occasional spotting every couple of months if that. Weight gain was a problem for me but I'm not overweight and I can lose if I stick to a healthy diet. Other than that I've had no problem with the depo, it's really not as bad as people are making it out to be. Once you get past the months of bleeding you don't have to worry about a thing. :)"
