They will become sexually mature at about 6 months old. If you do not want her to lay eggs (which you shouldn't while she's still a < a year old, because she's still growing herself) you should lower the basking temp to about 80-82*F and the ambient to about 75*F and feed her no more than 8-10 feeder insects every 1-2 days.

Then if you do want her to breed, raise the temps to 85* and feed her a bit more. But the temps should never be as high as you have them, I think that's way too high and not cold enough at the bottom of the cage for her to cool off.
Do you have a photo of her? It would be weird that you've kept her this warm and she hasn't produced eggs.
