abnormal uterine bleeding
"So I was on trinessa for about 2 to 5 years. I loved it for the first few years. My cramping  intensity went down to where I could go out and function without any problems. My period was very regulated to where I can predict the exact day and almost the time. It didn't help with my acne at all. After about 3 years I'm starting to have cramping again to where I have to stay in in the bed. And my regulation is off. So it's really good while it lasts."
