First we're going to need to know more about your setup. How old is the snake? What are you keeping it in? What are you using for heat, and how are you controlling it? How are you measuring humidity and temperature? What are you using for substrate?

As for right now, I would advise you to wait at least a week before trying to handle or feed your snake. They need time to acclimate to their new environments, which stresses them out a bit. That's probably why she regurged.
