Yellow vaginal discharge - hormone imbalance? Im so stumped 😩😿

So ive been to my 5th doctor after visiting my gyno, a sexual health nurse etc who all felt my discharge was normal looking. Ive had swabs done that all come back at candida but neg for everything else including clamydia, trich and BV. Ive never had sex, only recieved oral. Its stringy slightly clumpy, cloudy to yellow. No smell or itch. i do have polycystic ovaries and hormon imbalance (i get irregular painfuo.periods, suspected endo) and have suffered from discharge for a while and my mum did too. Ive done every investigation possible and I even asked yesterday if it was possible to get gonorrhwa from oral and the doctor said unlikely,my discharge would be much heavier and cloudier. So i just dont know if im over reacting or if i should ask for another swab. Ive even had a pap smear, a virgin...
