However, I can't say whether this might be causing your discharge
. Metronidazole and
other antibiotics can trigger yeast infections, but the main symptom of yeast is itchy irritation, not discharge. Up to 20% of women with trich also have gonorrhea or chlamydia, and every woman with trich needs to be tested for those infections. If not tested, or if your discharge persists, return to your health care provider for further evaluation.
