go seek help from a doctor. cause chances are it may be something that you do not want . so to be sure that it is or isn't something to be concerned about you should really get that checked out .
It sounds like thrush, quite common in women, but just to be sure if it is foul smelling then you should go and get it checked by your doctor :)
i recon you go and see a doctor, it could be some infection or diseas.
you probably just have a affection,,
