Don't toss it out. If it's not brett, you could add some. My guess would be lacto.
Either way taste it. If it's not too great (tastes sorta-infected) BOTTLE don't keg. If it tastes fine, keg it. If it's completely undrinkable, wait another two weeks, or add brett and wait another four weeks.
Just an extra .02
Marbles baby, marbles.
