What could be?

My dear doctor,

Here comes another question from your faithful virtual patient. I was on antibiotics two months ago ( clyndamicine) against a vaginal infection ( burning after urination and aboundant discharges). As i have been sexually active only once the doctor ruled out chlamydia, gonohrea, and under the microscope she said there is no fungus but there is a sign of infection ( didnt mention BV). Now 2 months after the treatment (i continue not to be sexually active) the aboundant discharge continues, not odor, but itching before and after menstruation, itching times to times. Been to another family doctor, she took a swab and said there is neither yeast nor bacterial vaginosis, but the discharge is not normal, there is an infection, so she refered me to the gyn (waiting for the appointment). I am very worried, what could be? The first doctor didnt mention to be BV, just a sign of infection (they were both family doctors). I was wondering could it be trichomonas? When they check for yeast and BV under the microscope they can not see if it is trich? Maybe they need to mix the discharge with another specific liquid(different from the BV) to check for trich? Do i have to worry about trich or if i had it they could have already seen under the microsope?
What could be that the discharge is not normal?
Waiting for your helpful suggestions.
Thank you very much.
Suela

Trichomonas is sexually transmitted as opposed to yeast and bacterial vaginosis.
Your doctors should have been able to see it under the microscope.
Sometimes yeast is difficult to find so you can try a yeast vaginal culture or try empiric treatment with oral yeast medication called Fluconazole. Sometimes with recurrent yeast infections it is difficult to eradicate the yeast and one has to be on Fluconazole for a prolonged period of time.  
I think it is worthwhile to see a gynecologist the next time you have the discharge and try and see what the discharge is.
