acne
"This is my 4th month on Trinessa. My doctor put me on it to help with my heavy and irregular periods as well as my acne. The first 2 months didn't seem to have any effect on me other than make me break out. In fact, this first period I had on this medicine seemed longer (around 7 days) and more painful than ever before. I even experienced a bit of sickness around the first week. But I kept taking it, and it has finally started clearing up my acne and the last period I had was only 4 days with minimal cramping. This birth control is pretty effective for me, and it's finally doing it's job. The point is: give it time to work."
