Good day, I am really worried about my menstrual cycle. My last menstruation was on January 6, 2016 and haven't had my next cycle until now, March 21, 2016. I'm worried if I had PCOS because I gained so much weight that it gave me stretch marks, had a slight mustache but not visible and no menstrual period. Please help me. I researched about taking pills but I think that factor that affected my menstruation was my obesity. thank you.
