abnormal uterine bleeding
"I took the shot for about a year but had to come off of it due to medical problems. While on the shot I bled very little if at all. After I came off of it, it's been 6 months and there hasn't been a day where I've stopped bleeding heavily. It's been a 24/7 period, everyday, since I came off of the shot. It also caused massive weight loss for me, nausea, and drowsiness. If you're thinking about taking it, there is no positive reason to, it doesn't keep you from becoming pregnant and although it gets rid of your period while you're on it, once you come off of the shot your period will not stop for months."
