She should be old enough now for full sized crickets.
By now you could be feeding her every second day as well.
You will want to watch how much you feed her too, because overfeeding them once they reach sexual maturity will lead to production of large clutches, and even folicular stasis and eggbinding, etc. 3 to 5 crickets every two or three days should be low enough to keep the clutch size low and maybe even stop the reproduction completely.
Temperature control is important too...basking should be 80F. This helps keep them less hungry IMHO and thus the "diet" (feeding schedule we keep them on to prevent the reproductive issues) doesn't seem so severe to them.
