"i started taking microgestin about 5 months ago. before that, my periods were already very light and now almost nonexistent. my breasts do get sore, but i have no mood swings and never get cramps. the only thing i&#039;ve noticed different about this pill is that for the past 2 months, i&#039;ve started my period a week early (before the placebos). i talked to a doctor and they said it was fine and may eventually even itself out. other than that no bad side effects."
