She does look like she could be gravid...it's hard to tell in those pics. With my female eastern who was gravid twice...as others have said, you will notice her getting very restless before she delivers and may have a shed right before. Mine also started hiding a lot and got quite defensive...she did not want to be bothered and would strike at me often....she was protecting her young. The first time she was gravid, she only delivered stillborns...30 of them. This past time she was gravid...she delivered 40...only three live. Before she was ready to deliver I put a nice big box she could hide in and some moist sphagnum moss in an additional hide for her. The birth process could take several days...to weeks depending. It took Cee Cee three or four days to have her live young and two weeks to pass the stillborns. Be prepared that you could get stillborns or even jellies (unfertilized eggs that come out looking like orange jelly or small orange jelly beans). I noticed when you changed her enclosure that you are using paper towels...she may want some kind of substrate to burrow in...carefresh is a good one. She may also need to be fed more than usual. I fed my gravid female every 4 days...2 to three pinkies or the equivalent in fish or worms. Have a separate container ready for the babies...something very secure...babies are great escape artists. I put a pile of moist moss in a corner for my babies for hydration and a nice big shallow water dish that they can drink from and swim in...but can easily get out of. I also make sure to keep them nice and warm...not too warm. I use a 40 watt household bulb in a dome lamp on one side of the enclosure and a 25 watt night bulb. Babies need to be fed often. I fed my newborns small meals....nightcrawlers or fish or pinky chopped into tiny pieces...everyday at first and then every two days after the first week or so. Supervise babies closely while feeding. Any other questions please feel free to ask!
