Not showing typical gravid patterns but she is gravid, not fat.
If she’s digging in the corner your too late for husbandry fixes. The only thing you need to be doing right now is finding a suitable laybin, trash bin is fine, and fill it with 8” of moist play sand. Not wet, moist. Slowly add water and stir until it’s like beach sand and holds a tunnel. Put her in it and place the bin somewhere where she can’t be disturbed and leave her alone. Check on her once an hour or so.
The husbandry fixes are important but irrelevant if you don’t get those eggs out of her.
