If you are planning to fix her anyways I would do a spay and abort , best option here especially with it not being an optimal breeding. then you dont have to worry about added expenses later on , c section cost if needed can add up to $1000 after everything, pups shots depending on vet could run $20-$50 per pup. any un for seen problems with the pups { I just went through parvo with a litter} it ran me $1200 and that was with a nice vet who cut alot of costs. spay and abort sounds best to me if you werent wanting this anyways. best of luck .
