She does look round, but i can't tell if its pregnant round or not!
I reccommend giving her lots of extra bedding and added protein and fat in her diet (mealworms, boiled egg white, chicken, peanuts) just in case she is pregnant. Also, removing the wheel now as if she is showing pregnancy pups will arrive soon, approximately in the next few days but thats just a guess.
A nice calm environment for her and playing the waiting game are the only other things I can suggest. You should hear the pups when they arrive, but don't touch or disturb the nest and keep handling of mum to a minimum. Continue the extra protein and fat if she gives birth. Then, pups will open there eyes around 14 days old, sometimes a bit earlier in ww's, and they can then be handled

Though they might try escape from the nest before then.
Hope shes not but best of luck anyway x
