I need help! I have been on Yasmin for the past 6 months. I never felt sick but my periods became more painful, had pains in my calf muscles, can't sleep or stay asleep, always tired, very moody, gained 20 pounds, got spider veins, etc.. It's terrible! I have about 9 pills left before the sugar pills start. I really want to stop taking it. Do I have to wait until the sugar week to get off? Or can I stop now, my moodyness is driving me crazy!
