Odds of contracting gonorrhea via recieving oral only.

Im a virgin, but late last year in my first relationship (im 22) we did nothing more than oral and i started to get an increase in discharge, no smell or itch. Ive been swabbed several times, had a cervical screening test, a test for clamydia all coming back negative. But i have not specifically been tested for gonorrhea. Every different doctor has concluded its physiological and extremely unlikely for me to contract it via recieving oral only. I have anxiety about this and doctors keep answering the same. Please be kind as for some reason many ladies here comment in a nasty manner. I'm a young 22 year old and I a bit of hypochondriac. Just thos dishcharge is very heavy, stringy, yellowish to cloudy and very continuous daily have to wear a liner.
