I am 15 and a virgin. I was on birth control for heavy bleading and cramping about five months ago. My doctor said that my period should be regular after three months on the pill; It wasn't. So, I stopped taking it about five months ago. I kept having a period, every thing was fine. Then last month (September), I never got my period. The same with this month (October). My period has never been regular, but I could usualy tell when it was coming; usually late in the month. But now, I am really getting worried! I have had some wieght loss, but not so mush stress. I know I can't be pregnet, but what else could it be?? PLEASE, PLEASE help me!!

Please and thank you,
