It depends on where the discharge comes from, but I would agree that you most likely have a fungal infection. However, discharge can be anything from a harmless ailment to a life-threatening condition. You should set an appointment with your doctor to get this taken care of soon.
Maybe it's just spotting between periods. Sometimes it's a brownish color and doesn't look like blood.
It could be a sign of a fungal infection. Have your doctor do a check-up. It could save your life.
