I have discharge that then dries kind of brown and stick to my pubic hair and my vagina itches?

Yeast infection: Typically, when there's itching it can be due to a yeast infection. Discharge that's brown is typically old menstrual blood. You can see a doctor or clinic and get an exam to test for yeast. If the brown discharge is bothering you, that is, if it's lasting for more than a few days, then you might want to consider some hormones to help regulate your cycle so that you don't have as much spotting.

Please bring this up with your Gynecologist who knows your medical history. If you don't have confidence in your Doctor see another for a second opinion.
