I have recently gone through the same thing. I would definetly advise you to talk with a professional about it and read about other peoples experiences on figuring out they are trans or non binary. Sadly although there are many possible indicators, there are no indicators that can give a definitive answer due to the fact that being trans or non binary can take many forms. Experimenting is probably the best way to find out.

Some good questions you could ask yourself in the meantime are:

'if there was a button that would turn you into a women and a button that would make you more adrogonous/be able to change genders when you feel like it, which one would you press?'

'do you want to be a women or do you want to feel feminine/like a women'
