Funky smell

Everyday i get a heavy amount of discharge, i dont really care about that. I just dont know why the smell is so strong and smells so bad, what am i doing wrong. I shower twice a day daily and try and drink alot of water but my discharge still smells really bad. I thought it was my vagina but the more it kept happening i figured out my discharge has a strong nasty scent every day ! Its so embarrasing. I can smell it even when im sitting down in class, someone please help :(
