"i was given two (months) free samples of this medication to regulate my extremely heavy &amp; long (month and a half) cycle. i have only been taking it for 3 days and immediately nausea, headaches, and mood swings have hit me hard! but after two days of taking the pill my period stopped. it is chewable and i was afraid of that but it has a really nice minty flavor. hopefully after about two weeks or so the side effects will subside."
