Does she look bloated? Whites don't usually sit in their water dish for long periods of time unless there is something wrong. If she is impacted she would soak in her dish to try to help things along.
How is your temp/humidity? It's possible your humidity is too low.
If you have pictures of your frog and it's enclosure that would help.
The only way to really know what is wrong is to take her to a vet. Save any waste you find in a plastic baggy and keep it in the fridge until you can get it to a vet to be tested.
How do you feed the crickets? If you don't already do so, put a few dusted crickets in a glass bowl in her enclosure at night and leave her be. Check in the morning to see how many she ate. She could might be stressed from being in a new environment and then moved to another tank just for feeding. I would leave her in her normal enclosure with the glass bowl and see how she does.
