Does Seasonique Birth Control Pills Cause Cramping And Green Stools?

Ive been taking seasonique birth control for a little over a month now. And ive noticed a lot of cramping. I take it at 9pm. then the next day during mid day i have to go to the bathroom RIGHT away. I never went number 2 that much it went from once or twice a week to like 4 or 5 times a week now. and ive noticed my poop is green. it even turns the water in the toilet green. Should i worry ?
