abnormal uterine bleeding
"I first had this shot in 1997, I had two but felt sick all the time, my periods did stop though. Came off it and went back on the pill, didn't have a period for a year and a half. In 2000 I decided to give it another go, soon settled down and didn't have any periods at all, stayed on it for 14 years. It was fabulous, no periods or spotting. But, I was suffering from depression which is a side effect of depo I decided to come off it. Started my first period after about 10 days and it lasted about a month and it stank. Had about a weeks break and then bleeding again, thick dark brown clots. In the end I gave up and went back on it, after 3 injections still having random spotting, lasting random amounts of time. Just hope it settles down again"
