H. carolinensis ate sac again!!!

This particular spider has been in my collection for around 6 months. She had her first sac a few months ago, which she ate after a week or so. I assume infertile?? The second one lasted almost two weeks, and it disappeared overnight.. Is this specimen just unable to produce spiderlings or what?

May just be infertile, mine does the same thing.... Does she have enough substrate to burrow? They like to have a safe spot especially when carrying eggs

Yeah, she has had a burrow about 3 inches deep for a while.
