Get your doctor / gyno to look into you having polycistic ovarian syndrome. It is a condiditon where the body does not properly use insulin and results in small cycts on the ovaries where the eggs do not properly erupt and hormones are changed within the body.

Other signs of PCOS are excessive body/facial hair?

I would strongly recommend seeing someone, get some tests done. It could be that you are extremely deficient in iron. It could be PCOS, it could be thyroid problems.....go and see your doctor... good luck.
