VAGINAL discharge light yellow\green, stretchyno itch,no STI :\

so ive been having this thick stretchy discharge , NO ITCH NO ODOUR, just this increase in dishcharge since september last year, got tested positive for candida\yeast infection twice treatment hardly worked. had no itch. anyone think this is normal? im ovulating today and its very stretchu, light yellow to light green, no smell. ive been tested negative to Trich, Clamydia. never had sex im a virgin, ice only recieved oral and a sexual health burse said it could just be physiological discharge, but the colour is what frustrates me. i have to wear a liner every day. ive literslly had so many swabs done all coming back the same, neg for all std's (only one i havent been tested for is gonorrhea). am i overeacting? could it be vaginitis?
