I started taking maca 3 months ago to help get rid of the cramps and balance my hormones . The first month was fine it actually shorten my period and no cramps with lots of energy. Second month period consisted of 4 light days 3 heavy days and a few more light days still no cramping. This month I had a few light days and 10 days of heavy days and still going. I amd concerned about when this will balance out. I stopped taking the maca hoping I would immediately stop menstruating. When should I see a doctor for this?
