Keep her warm, wet and clean until you can get her to a vet.
The dehydrated/ constipated snakes I have helped out sorted themselves out with this, and worms (wet food) but it sounds like you have more going on here.

Id keep her as comfortable as possible, and allow her ample opportunity to rehydrate herself and get things moving on her own- I wouldn't push things along any further.
Vet if and as soon as you can manage.

I hop things come out o.k.
