For what its worth, I remember when we fostered Petree (a hybrid who we knew was pregnant when we said we'd foster her). Its exciting but terrifying isn't it?
It worked out well for us and Petree and I'm sure it'll work out fine for you and Gimli too
Good luck waiting until pups wander if she has them though... We're waiting for mouse pups at the moment (new pet arrived pregnant) and we're at that time where they should start wandering soon so I'm having the odd hour where I'm rediculously impatient now, then I go back to being patient for a bit... And then I'm really impatient again
The ham pups saved me from this by wandering a bit early, the mouse pups are getting near the later end of normal now and its driving me a tad bonkers lol
