Alligator lizard gestation period

Question
I have a pair of Alligator lizards and they just mated. How long is the gestation period?

Answer
 I would need to know which of the 67 species of Alligator Lizard you have.  Most are egg layers and will start laying approximately a month after mating.  Incubation ranges 70-90 days depending on temperature in the incubator.
 The Northern Alligator Lizard is a live-bearer, and will give birth between 3-4 months after mating
