abnormal uterine bleeding
"One thing for sure. It definitely prevents pregnancy because you can't have sex due to the fact you're constantly bleeding. I got my  second shot on July 10th and I have been bleeding ever since with occasional clots and it's almost the end of August. It's very frustrating and annoying. I definitely will not be getting the third shot! And the medical facilities that provide the shot have no clue. #neveragain"
