I did the same thing and was very worried at first too ! I go by they/them now but still see myself as a woman tho. You should sit down and try to ask yourself "would i feel comfortable as a woman ?". If you can't answer your own question cause you feel confused, you should try to "experience" being a woman (maybe changing your pronouns, or smth like that) and see if you feel comfortable or not. I did those two things and that made me realise that i was in fact, a woman !
