Vaginal odor please help thank you

So I noticed I have a weird smell coming from my vagina sorta like a sweaty smell. I bathed in apple cider vinegar for 2 days already and it’s gone but it does come back a few hours later my vagina lips have been red for months now and no cream has helped me with that I’ve been tested for stds and I don’t have any but I’m currently wondering if it’s bv or yeast infection. Does bv make your vagina lips red? And if it is a yeast infection what creams help with making the redness go away.
