Have you puppy proofed your home, meaning, are all wires, cables out of her reach.
Make sure what you value is not in her reach, other wise it will be in her mouth.
Did you buy a tube of Nutri-Cal for just in case she gets Hypoglycemia
Did you buy the same food the breeder is feeding her, she should stay on the same food she is use to other wise she will have stomach issues.
Are you keeping her in a play pen like an xpen or Iris pen, if not I suggest baby gates to keep her out of rooms when you cannot supervise her.
Never leave her alone without supervision.
Do not give her free roam of the home until she is 100% pad trained.
Did you make an appointment with your vet for 24 / 48 hours vet check up.
If not I suggest you make that call now.
Make sure the area she will be in has nothing laying on the floor, these puppies are just like human baby's, everything goes in their mouth.
Get plenty of sleep tonight so you can keep up with this little bundle of energy you'll soon be bringing home lol.
