abnormal uterine bleeding
"I've been receiving this shot since October 2015 and it has worked very well with little complication. I've had about two or three bouts of random bleeding (which might have been my cycle. I lost track of it) but they did come with normal PMS symptoms like mild cramps and fatigue. I did gain a little weight but I'm not too concerned  about that. I was on the pill for a while and this has given me so much better results. The pill had terrible side effects (emotional and physical) and I hated having to remember to take it everyday. I was given a full tutorial of sorts about each type of birth control, what to expect with each, and how often it's taken. I did not experience anything that I was unaware might happen and haven't missed a shot."
