I've had very foul discharge for over a year. went to doctors and she said i should take probiotics, but what more can i do? (it's not bv)

Odor: Probiotics might help, but a product called rephresh ph may as well. Organic yogurt douches may help (home made yogurt mixed with sterile water to make slurry inserted into the vagina). I also recommend avoiding thong underwear (increased BV and e coli infections), underwear off at night to allow perineum to dry out, wiping front to back and no unprotected anal sex.
