Hi there! I have had a white/light yellowish vaginal discharge for 3 months now. No other symptoms. IT tastes sour. I ve taken chlotrimazol, then metronidazole, no luck. I went to a sexual health clinic and they did a blood and urine test for chlamydia etc, it was all negative. Now I ve tried suppositories that are meant to balance out the flora in your vagina for the 6 days prescribed - again no change, I still have the discharge. I eat healthy - lots of fruit and veg, don t drink much alcohol or fizzy drinks. I dont know what to try next...
