"I recently switched from LoEstrin 21 to Trinessa. It has only been a month exactly, but I have zero complaints so far. Totally cleared all my acne that I continuously got from my last birth control pill and absolutely no breakthrough bleeding as well. I was nervous to switch after reading many negative reviews but it is the best switch I made. I am much happier on it, and haven&#039;t gained any weight on Trinessa."
