Yeah, make sure you've given her enough time to settle in. The way I prefer to deal with any new snake is I don't handle them (unless I need to clean the cage or something like that) until they've taken 2 meals in a row for me.

From her behavior it sounds like she's just nervous. Once she's settled in and started eating for you, then you can just handle her regularly and she'll get used to you. But DON'T handle her for at least a week right now to let her settle in.
