QUESTION: Yes, she hasent been in the tank since mating
Sure can see the eggs

Answer
Hmmmm, well gestation is 30 days and she's right at that so...  If you are 100% positive as to the length of her gestation AND she hasn't laid by day 33 I would find a vet to give an injection of oxytocin which will induce labor.  I know of no "home remedies" for your situation.
