abnormal uterine bleeding
"I got the shot because I thought that I was pregnant and when my doctor told me I wasn't she told me that I should get on the depo shot because my periods were always heavy. And my cramps were always bad. She told me that the depo shot would stop me from getting pregnant and would also stop me from getting period. So of course I agreed because not getting your periods is like a dream. It went well for about two weeks and then on November 23rd  came on my period at first it was light then the next few days it got very heavy and the cramps are even worse. I'm still on my period and its been two weeks now. I've gained weight and attitude has gotten worse. Me and my boyfriend argue almost everyday. and sex? who wants to have sex on their period"
