Please help me lol

Okay so I hope this isn't gross or whatever but I am constantly smelling like a bit fishy down there and I don't know what it can be because I shower everyday or whenever I feel nasty especially in this heat and I've gone to the doctors got tests done and nothing she said eat yogurt more and that actually helped but I got tired of yogurt . It's not too strong of an odor like a slight shrimp ? Anyways anyone know what I can do or what this is or how or whatever please comment !
