Leo Ready To Lay Unfertile Eggs HELP!

[PDDM]

I need to know how to tell if my albino female is gravid,shes been getting real fat in her stomach but not tail...also i think she might be ready to lay because it looks like there are eggs in her stomach they are white orbish things in her stomach,But i got her in december...and she had colour maybe she was 2-3 months old...and she hasnt been with a male so the eggs will not be fertile...shes gonna lay anyways right?But anyways im scared now what can cause a leo to become egg bound and etc...this laying eggs sounds dangerous and i think mines gonna lay her first clutch ever soon she is on repti-sand... how much calcium should i be giving her and what kind?

Ok how big should the orbs be???And also...Shes on repti-sand is this bad???Its not calcium sand repti sand...no calcium what so ever...but she eats ALL her food in her tall mealie dish...but that being said i cant dust mealies...how much should i dust her food out of a week...also instead can i substitute by her licking the calcium off my finger?If not ill buy cricks...i get her to eat them by throwing it into her hide with a floor surface(not sand)
