acne
"This is my third month into Trinessa. I can't say I hate it, and definitely can't say I love it. During my first 2 weeks I experienced very awful breast tenderness (making roller coasters at the time not a pleasant experience) and some nausea and major headaches. My first period on this was a little hellish, but my periods before the pill were 8 long, heavy days. I was put on this pill for my acne. Before the pill, I always got acne before and after my period on my forehead (cystic) and when I started this pill I started only getting whiteheads (which is doable). It's the week after my period, and for 3 long weeks I've had awful cystic acne on my chin and forehead. I am planning to give the pill at least 3 more months."
