Your light periods can have a lot of causes, like stress or a change in your lifestyle or diet, but it could also point at some disease. The best thing to do is go to a doctor, so you'll know for sure.
could be Polycystic ovarian syndrome, a disorder where many women don't get their periods. http://womenshealth.about.com/cs/pcos/in...
