worst case scenario, you'll have bottle bombs. (They'll overcarbonate to the point of exploding)
Not sure what to do, unless you want to put it back into the fermenter, let it ferment out again, and re-prime and re-bottle. May be a way to crack the cap to vent pressure after so-many days, and then let them re-carbonate. Would be imprecise though.
