In about 3-4 weeks your female may lay a clutch or 16-23 eggs.
When she starts digging around her cage you should separate her into a containor (large rubbermaids work well) filled with 7-12 inches of moist sand & vermiculite for her to dig around and lay her eggs in. By this time, you should be able to feel a few eggs in her tummy and know for sure she is gravid.
When she lays, carefully remove the eggs and incubate them at 82-84 degrees F. and they should hatch in 65-75 days. 
Good luck and keep us posted!
You may want to but an incubator now so you'll have one if she does lay. 
How old is your female and has she bred b4?
