I had swine flu last year whilst pregnant (although I was full term) and went into spontanious (sp?) labour, Bubby was born healthy and didn't show any signs of being sick, I was still allowed to BF her, I was just given the meds to help get over it, and there is a pregnant safe one they can give her...

try not to stress to much, shes in the right place being in hospital, they will keep an eye on her, and only induce if they need to.
