Hello and welcome to the forum!!
It can always take time for a new hammie to settle in. If your hamster is nipping you try and wash your hands before handling her. I sometimes find my hamster nibbles my fingers when he can smell food or something interesting on them.
To help your hamster get use to you, you can sit in a bath tub if you have one and let your hamster run around and use you are their climbing toy.
I can't wait to see some pictures of her!
