abnormal uterine bleeding
"I was on the depo for about a year, everything was perfect. Then I had stopped taking birth control, went back on the patch, then I had to go back on the shot. Now, I'm due for my third shot and I've been bleeding for two weeks. Every time I think it's done, I become active with my partner and it all starts coming out again! He and I have been together for a year and a half, so the only good thing about it right now is that I'm not pregnant."
