You DEFINITELY DO NOT want to feed tomorrow. As the others have said, wait at LEAST 2 weeks prior to feeding again and offer smaller prey than the typical size rats she usually eats.
Also, like the others said, double check your husbandry, heat sources, etc...
What are your temps? How do you heat the enclosure? Are heat sources regulated by a thermostat? How are you reading temps? And where are you measuring temps?
Hopefully, all your husbandry is solid and this was just a fluke, it happens. If husbandry is on point and it continues, definitely see a vet.
