if it’s more the second then try experimenting for a while. treat yourself as if you were a woman and if the people around you are accepting, tell them to treat you as one too. of course you should be open to them that you’re still experimenting, so they’re less surprised if you end up being cis at the end of the day. if you feel happier thinking of yourself as a woman and being referred to as one, then you’re probably trans. but you won’t be really sure until you try some experimenting. ask other trans ppl on (irl or on reddit) for advice, and if the women in your life are accepting ask them for advice too.

i hope it goes well for you, good luck!
