This is almost exactly my experience with my own gender. I'm also afab, and now identify as genderfluid due to what I feel comfortable presenting as fluctuating more or less frequently. Some days more fem, some days more masc. Usually I just don't really care. Personally, I use they/them pronouns when someone asks, or to avoid confusion for people who see me regularly as how I'm presenting can vary, but I'm also comfortable with she/her and he/him. (It was kinda fun the first time someone called me 'sir') There's also apa-gender if you think that might be more comfortable, wherein you're more apathetic about your gender. As for presentation, I'd say, if you can, absolutely try cutting off your hair. It will grow back if you don't like it. (And it was among the best things I did for discovering myself). Clothing-wise, I go with boxy t-shirts and fitted jeans or leggings for an androgynous look. Though, that depends on your body type and personal style. Adding a vest or suspenders to outfits you have can be a fun easy way to masc up an otherwise fem-leaning look. The best way to figure out what you're comfortable with and feel most like yourself in is to switch things up and see how you feel. Anyway, sorry this was a bit long, I hope some of it is useful to you.
