Since no-one knows EXACTLY what hatchlings do underground after hatching, I would say just continue observing the nest on a regular basis.
If I'm not mistaken, much of the data on incubation periods we hear about most frequently was collected under laboratory (ie: controlled) conditions: steady temperatures, humidity, etc. It may take a little longer in a natural setting, and, just because the eggs have hatched doesn't mean the little ones are ready to dig out yet.
In real life, soil temperatures fluctuate, the ground hardens due to lack of rain, a late clutch of eggs may hatch and overwinter in the nest... you may have a few more weeks to wait before you see little ones come up. That yolk can sustain them for a VERY long time.
