Discharge is caused by the changing level of hormones in the body. Symptoms like itching, a strong odor, or a change in color (such as to brown, gray, or green) indicate that a girl may have a vaginal infection and needs to see a doctor.
Monistat is a fairly effective over-the-counter ointment for yeast infection, but If your symptoms do not go away, you should then see your medical provider for an exam. These infections can often reoccur; a woman's body may become drug-resistant to yeast infection medication, and the real problem is never treated.
Therefore, you should consult with your Doctor; you may require a prescription, cream, or suppository treatment from the pharmacy. A more precise treatment can always be made when samples of vaginal discharge are obtained for examination under a microscope.
Hope this answers your question!
