Yasmin says it shortens and lightens your period but this is NOT TRUE! I have horrible cramps for about a week before I get my actual period, the flow lasts for about 5-6 days (on a different birth control mine lasted only 3 days), and it is extremely heavy. I have terrible headaches that cause me to feel dizzy and I often lose my balance. I am always tired and have no motivation. I absolutely HATE Yasmin and I am so glad that I am switching off it. I would NOT recommend this pill to anyone I know.
