TmI? Clean and healthy but i can’t seem to get rid of this fish smell??

i’ve been dealing with this for a while now i have an appointment with an ObGYN the 29th to check everything out but i feel so embarrassed going out in public, work being around my boyfriend or friends and having that smell, i’m a pretty clean person i shower regularly change my underwear i’ve used vaginal wash ( for the outside of course )but nothing seems to make the smell go away do you lady’s have any tricks or advice that would possibly help me out till the doctors can??😓😓😓
