Why am i have brownish discharge?

I honestly doubt it but I am not a doctor. If it bothers you that much, you're at the doctors department to enjoy it removed anyway...why not ask them while you're nearby? They can make a contribution you a more accurate answer and possibly a solution if they surface it's notably possible
