I'm sorry to read about your worries...Hopefully she's okay, but it's always good to run blood and urine tests (esp. if you're concerned with her water intake/urine) to make sure everything's okay. If it were me, I probably would not limit water intake because I feel that they should be able to drink water when they're thirsty, just like I want to be able to drink water whenever I want
If they want water, they probably need it.
Good luck, and I hope everything is okay!!
