Give her a week or so to settle in. During this time don't touch her and try not to spend a lot of time staring at her. Give her some space and some time to become comfortable. Try to keep everything as a routine- it will help her learn what to expect and reduce the stress of acclimation. Feed and water at set times for a while, and turn your lights off and on at the same times every day.
Once she is feeding and pooping regularly you can loosen up the schedule a bit and also spend time enjoying her and observing her.
