Can I be demigirl and non binary at the same time?

Recently, I am not so sure what should I label myself have right now. Around 13 years old I label myself as non binary due to not giving a damn about any genders. When I turn 17, I call myself demigirl because I slowly leaned towards feeling like a girl​ but doesn't fully feel like a girl. Now, I'm feel like a mix. Like there's time I can feel like a girl yet there's time I couldn't feel like a girl, nor do I feel about any genders.

It feels right to have these 2 labels on me, but I am not sure if I can do that​​
