Hamster dehydrated?

I was really STUPID. For some brilliant reason I forgot to check my hamsters water bottle. Last night when I was bringing my little Bindi Sue over to my neighbors house for a hammie party, I realized that her water bottle was completely dry. Immediately I got her water and she was attacking the water bottle and drinking thirstly. She was jamming the spout into her cheek pouch and everything for a minute or two. I squeezed the water bottle for her so she wouldn't have to work to hard. She took a brake from drinking and then did the same thing agian. I felt soooooooo bad. I think she was out water for two days. My room stays pretty warm because I keep my door shut to keep my other pets out. She doesn't normally drink to much water so I am not sure. She has been acting normal but I was just wondering if I should watch for anything. I am now checking her water bottle 5 times a day!
