Hello. Ive Been Concerned About My Period For A While.

Hello. Ive been concerned about my period for a while. Ive been spotting evry day for over two months. I had a heavy period only once. I am a little scared. I also been loosing alot of weight. Ive Been over weight all my life and my period was never normal i would get it evry 4-5 months. Im not sure if my period is not going away because im loosing weight. Or if im loosing alot of weight because of my period.
