Could I have gotten her Lice?!?!?!?!?!??!?!?

Itching is common when you think you may have gotten them, just because. But they are contagious, I would have someone in the family look at your scalp and also I would most likely go to the school nurse. But please know that they can spread to other people in your house, so this is not a time to keep a secret. Now if you do have them, it's not your fault.
