Vvvvvfl?

Vvvvvfl? At first this test looked negative then I looked at it again maybe 15 minutes or so later and see a faint line? Do faint lines form and give false positives after an extended amount of time? I pulled my one from yesterday out the trash and it doesn't have a second line..help please?
