"i have switched to this medication because they discontinued micronor which was perfect for me. when i started taking blistovi i had headaches and any birthcontrol for me never makes cramps go away except for micronor. so i still had cramps. a little bit of weight gain. i was super emotional and moody. regular 5 to 6 day periods. after taking these pills for about 4 months, the side effects got better. i barely get headaches. my period is lighter than it has ever been. 1 to 3 days. the only time i&#039;m emotional is on my placebo week. and i am not pregnant :) overall it&#039;s a tolerable pill."
