Too Much Discharge.

Hey, im kinda new here, so im not sure what kind of help I will get, but I hope for the best. Well, I havent gotten my period in 2 months, and im worried. But the thing im worried most about is that im getting a lot of discharge. Sometimes its chunky and it smells bad, but its white...But I have to change my underwear a lot. Its really annoying and I dont know what to do, and I read about it, and one website said that it might be because of eating disorders, but the eating disorder I had lasted only for 2 weeks and I wouldnt consider it a disorder. And I dont see how that could have anything to the discharge problem, since I didnt get my period in so long. And dont masturbation have anything to do with it? Please help, I cant stand not knowing what to do!
