abnormal uterine bleeding
"I was put on Tri Sprintec when I started getting my periods every two weeks, and was on it for three months. It fixed my period problem, but I had never had a problem with acne until starting this. My acne got so much worse and would clear up instantly once I started the sugar pills. I went from a D to a DD which is kind of annoying but I didn't gain much weight at least. The worst part, however, was the tenderness in my breasts, it was horrible. Painful to the touch, running or going to the gym was horribly uncomfortable. Just like the acne, during the fourth week on sugar pills the pain disappeared only to return again with a new pack. "
