Your eggs are able to fertilze as long as they are 18cm or larger.  Typically eggs grow about 1-2cm a day.  She may need some meds to help her stimulate ovulation.  I took clomid and had the hcg trigger shot.  I had 3 eggs (13.5, 18.5, and 24) which means only two would have the chance to fertilize.  Tell her good luck.
