She is probably still a little scared and the bed is a big wide open space so she will be seeking cover. Maybe in you make some hidey holes withe the duvet and pillows she will enjoy exploring around these. Ours sure do
Try not to swoop down on her or loom over her as this sets of an alarm signal instinctively in a hammy and the will either freeze or run away seeking cover (Like an eagle is swooping down on them)
You sound to be doing well for having had her two weeks so your taming is working. Well done
