can i be transgender and gender non conforming?

google won’t give me any answers so i took to this app. it’s just that i’m definitely trans, no questions about that and he/him pronouns only, but i’m not really that masculine. and like some days i feel more masculine and others i feel more feminine (which led me to believe i was gender fluid a few years ago 😂). the main thing i’m scared about is that people won’t take me seriously because of it. oh and also, and i know that this sounds kinda stupid but i was thinking of maybe getting a big pin that says he/him because i don’t pass, do you think that might help not getting misgendered all the time?
