I started seriously dieting and exercising a few months ago... I have lost at least 3% body fat during this time. I have also been on orthotricyclen for 2 years, without any problems...until lately. My period has come a week early(when i'm still taking active pills) twice in the past 3 months. It lasts at least 7 days when it does this. Would this have anything to do with decreased body fat? and has anyone else experienced anything similar?
