Confused about gender

So I started T four and a half months ago and that was one of the best things I've ever done. But the last month I have been questioning my gender again.

For more context (if necessary) I am 20 years old and have thought I was a trans man for almost 5 years now, but recently I have been questioning if I might be a demiboy, or somewhere under the non binary umbrella. Gender is just so confusing at the moment.
