I'd say she has eggs and is close to laying them for sure. Has she been pacing around the cage or digging at plants/floor? As soon as my females begin to do that I move them into a large garbage can with a foot of wet sand (not soaking but able to hold a tunnel). You can put a webcam or old phone in there to observe them but it's best to give them complete privacy. She should lay them if it's not too late and will need a good watering/feeding and lots of calcium when she's finished.
