When you ask "does it work?" what is it that you want it to do because according to everything I´ve read it has loads of effects including increasing CM, making cycles more regular, reducing PMS symptoms, improving skin, hair and nails...
I started taking it 3 weeks ago when I stopped my BCP as I heard that it can help your hormones to settle down and for cycles to return to normal much quicker. I´ll let you know next week if I get AF but at the moment I can definitely say that my hair and nails are thicker and I´ve had no effects after stopping my BCP (everyone else who has stopped taking Yasmin seems to have suffered from weight gain, mood swings, acne and hair falling out!).
