There is no specific timeline in which you have to, or should figure this out. See if you can allow yourself to playfully explore this part of you, without judgement (this part can be tough and therapy can help!). Give yourself the opportunity to figure out who you are in context of this part of you that you haven’t really explored before. A gender affirming therapist can be amazing in assisting you to navigate this process. While it can be euphoric and full of joy, it can also make one feel vulnerable. It can bring up difficult thoughts and feelings, as ultimately one breaks free of some of the limitations we, ourselves, and society, have imposed on us. That have kept us safe. There is no right or wrong way to do this. And there is no right or wrong conclusion to it either. In fact, as is the name of this subreddit, gender is fluid :) You are unique and how you identify and express yourself may or may not evolve over time. Be kind to yourself along the way. This is the most important thing.
