Just to clarify, the term ''non-binary'' refers to any gender that is not just male or female.
Also, it looks pretty similar to genderfluid, i don't know if i'm right but this can help:
Genderfluid is when your gender can change between certain periods of time from hours to years. Another possibility can be genderflux, which is basically genderfluid but with various amounts of percentages, and usually much subtle transitions.
It's still up to you to define your gender, but i hope i can help just a little bit.
