How old is she? Have you checked your husbandry in terms of supplementation and heat? I have 2 pairs of banded geckos. One pair has produced 8 live hatches this season with 2 more in the incubator and the other has produced only 2. As long as husbandry is correct, I recommend trying again next season (I have more problems getting them to stop laying than to start) and if there's no success, getting another female.
