Hi there Vaginal discharge in a sexually active female that is malodorous is usually treated with empirical broad spectrum antibiotics i.e. three different drugs that cover numerous different bacteria. In certain cases a topical gel like metronidazole gel can be used. I am unsure why you were treated twice for a urinary infection, although this is common in females, it is unusual to have a persistent discharge from a urinary infection. I suggest you do a urine test to rule out an infection. Ideally you should visit your doctor and receive antibiotics for vaginitis. If the discharge doesn t clear you can send off a sample of the discharge to the lab to identify the specific cause. You should also have your doctor do a vaginal examination and once the discharge is treated, have a pap smear to rule out cervical disease from HPV. Hope this helps.
