Pregender

Pregender is a state in which one is growing into but not quite at a particular gender, or is moving to identify as a gender but has yet to fully embrace the term. One may feel that their gender is transitioning towards, but has not yet reached, that gender. For example, a pregirl/prewoman may feel like their gender is growing into, but has not quite reached female.

It's the opposite of postgender.
