How To Alleviate Excessive Menstrual Bleeding?

I am a 22 year old female. 5'4 and around 175lbs. My period was late for almost a year but I am not pregnant and the hormone pills my gynecologist gave me didn't help. I started what I think may be my period on Jan. 1st, 2012 and I am still bleeding but its really heavy and I am feeling sick. I don't have insurance to see a doctor so is there anything I can to to alleviate the excessive bleeding?
