What is wrong with me??

Amber

I have weird clumpy/off white/grey discharge and itching and my OB/GYN thought it was yeast after examining me but everything was negative!! I have an elevated level of white blood cells which indicates infection, but if it’s not BV, yeast, or trich then what?! My only sex partner ever is my girlfriend and the odds of STDS are pretty low because we don’t make contact with each other’s vaginas or anything. Could I get chlamydia or gonorrhea through oral sex and experience vaginal effects? I’m really worried that it’s something bigger wrong with my health. I’ve been making trips to the doctor about it since november...
