I was on Alesse for years. I never remember any side effects in the beginning. But then I started having light , but continuous breakthrough bleeding. My nurse put me on Yasmine. At first I didn't realize I was haing side effects until they got worst: breast tenderness, weight gain, breast enlargement, extreme weakness, irritability, contact irritation. The side effects went away for the most part, but my boobs and hips are still much bigger. I am thinking about tryin Aleese again
