Suggest Treatment For Periods With Clots And Pain

have not been feeling good for about 6 weeks now...normal periods are heavy with clots and extreme pain due to cysts. In October i started what i thought would be my period but it only lasted one day and the following two days only brown when i would wipe. Since then i have been extremely tired, nauseas, and extremely hungry. Normally i can last a whole day without needing to eat but now i am constantly starving. What could possibly cause this and is it normaly to have cycles like this?
