I'd have a reputable vet spay your girl that is more concerned about her welfare than cute puppies. Then I'd give the bill to the vet that said it was okay to breed her. If the new vet thinks it's unsafe to spay right now, then keep the number to the nearest ER nearby because it's likely you'll be needing it along with a couple grand for a c-section. If (God forbid) she doesn't make it or can't nurse (could have major issues with milk production - she is tiny), then you'll have to feed the pups, even through the night - every couple hours for weeks. I'd start planning now..
