Sometimes they do start to hide away after the first time out of the cage, it can be difficult when they don't give you much chance to interact with them like this but it's still very early days so I would just keep doing what you are, give her a chance to regain the confidence she had, just go back to the start with talking to her, even if she runs away, you could try leaving a treat in the cage when she does that so she should begin to get the idea that you talking to her & being around the cage means she gets something nice.
She should gain confidence again soon.
What's her cage set up like? Does she have plenty of little hideouts & safe places & not too much open space in the cage so she'll feel safe when she's out?
Does she have a sand bath? It's important for them to have one anyway but they will often pee in the sand which makes spot cleaning a lot easier.
She may be using the wheel at night when you're sleeping.
