abnormal uterine bleeding
"Awful. Awful. Awful. I started on the pill when I was 15 because I was getting cramps so bad I was almost throwing up from the pain. Now at 25, I am still using the pill but have switched a few times. The brand that I am using now is terrible. Horrible cramps, periods last for a week or more, spotting, mood swings, weight gain, acne, discharge... you name it, I've got it. The pill is effective for birth control, I'll give it that, but there are a lot of negative side effects that come along with it."
