I am a 17 year old who is not sexually active but I have been fingered if that makes a difference. Since my last period ended, I've experienced drastic changes in my vaginal discharge. It is a brownish color with a very strong, strange, almost nutty odor. It happens so frequently that I have to wear a liner/pad all day every day. But I have no pain, itching, burning, or anything like that. What could it be?
