What does dark brown vaginal discharge mean? (My daughter won't see the doctor)

If your daughter is under 18 I don't see how she has a choice in the matter. Be the parent and take her in. Infections, if left untreated can lead to serious problems. You, as a parent, need to step up and teach your daughter that we all have to do things we don't want to do.

You asked this yesterday and received several responses including one from me.
