Can you be trans if your behaviour is still mostly coded like your birth gender's (as stereotypical as that is)?

I'm seriously considering the possibility I might be a trans girl, but what really, really bothers me is that I don't really behave in a "feminine" way. I know that "feminine behaviour" is kind of a really stereotypical way of thinking, and I'm genuinely sorry for that, but it still worries me...

Ok so firstly: thank you for the overwhelming response everyone :)) I really, really appreciate the thoughtful replies and advice, and will definitely be keeping it in mind when the question pops up again

Secondly: I wanted to say that I'm incredibly sorry if anyone felt hurt by my question, it's just something I needed answered.

Lastly, I want to clarify some things.

As a relatively recently graduated historian, I kinda feel ashamed that I didn't think of the fact that absolute "gendered behaviour" doesn't exist and that it's all relative. I guess what I meant was more "what society often perceives to be gendered behaviour" (hence "stereotypical"). It's just that some trans women seem to pick up on that from a relatively early age, and I was a bit worried that this wasn't the case for me.

On top of that, what I mean with behaviour is mostly stuff like mannerisms, way of speaking, some thinking patterns, emotions etc. (like most of my friends are male, and I feel like I talk and usually think like a guy, even if I don't want to). When it comes to hobbies and interests: I didn't really think of them (I guess some of them would stereotypically be considered "male", like gaming, ancient history etc., but definitely not all of them, like aerial acrobatics, feminine clothes, photography, theatre etc.)
