If she is on the warmer side or near it most of the time, I'd say she's gravid. Up the ambient temps a tad to get it around 82. Keep it that way and watch for the next shed. That'll be her prelay shed.
See if she'll eat a small in the meantime. Some will eat, some won't...If she doesn't, that's a good sign she's holding some eggs.
I can go into much further detail if needed if you wish to call me.
Good luck!
