i've havent had my period since dec.23 2010. In the beginning of jan i had spotted for 2 days. which i just fig it was ovulation bleeding.the week before my period was due i had spotted brown stuff and that was it. the week it was due i just cramped. since then i took 3 or 4 preg test which came back neg. so i'm ruling pregnancy out. So can you tell me what you think might be wrong with me? my symptoms since my last period has been extreme fatigue, slight cramping, headache, super hungry, back pains and moody. could it be a cyst?
