If it's only a couple days, give her some time to adjust, at her own pace. Try speaking gently to her and approaching her slowly. Some puppies get frightened by quick movements. Make sure you feed her the same kibble from your breeder for the next couple months to prevent upset stomach. They usually bond with you a bit if you hand feed them.
Scottie was super scared when he first came home. It took him some time to adjust. So don't worry, you're not alone.
