We don't know what to think anymore

Hi everyone!
Me and my boyfriend got an Oustalet 3 weeks ago. Sorry for the long story, but I want to tell you everythig so that you can help us.

I came back from work 2 weeks ago and she had dug a hole. We put her a laying bin, we covered her cage thinking that she might need to lay eggs, but she did nothing.
She dug a hole again 2 days ago and another one today, but not in her laying bin. The reason I posted the thread here and not in the breeding section is because we don't know if she really needs to lay eggs or if it is something else since she does not look gravid at all. She is acting normal, she never stopped eating and she really does not have a big belly. I have read a couple of posts in which people said it would be obvious to tell if she was gravid by her belly size, but she does not have a big belly.
We dont know what to think anymore about her digging, is it because she does not like her enclosure? Because she just wants to get out? Could there be another explication?

I joined a picture that I took from her while standing on her laying bin and eating so that you can see what she looks like.
Thank you in advance, we are starting to get worried

She, looks like a HE to me. How old is he/she?

We don't know exactly how old she is, she measures 11 inches with the tail and we know she is a SHE because she is an Oustalet and female oustalets display more colours than male. Male oustalet are usually white, brownish, black, etc.
