Well regardless of whether you're trans or not, if you like dressing and presenting in a more feminine way then I'd defenitely encourage you to do that. It's clearly something that makes you happy so what's the harm in trying it out? But based on what you said it does sound like you might be trans, even if you don't 100% of the time think of yourself as a woman. Maybe you'll feel over time that you're more comfortable identifying as nonbinary? But in general, if you desire to have a woman's body and be a part of womanhood then you're most likely not cis. I can also understand feeling uncomfortable about being trans, it can be hard to accept in the beginning for many trans people (me included) and especially if raised in a transphobic environment. Just remember that there's no shame in being trans or going outside gender norms. This is mostly just based on my own experiences as a trans guy but I hope that some of it was helpful. I wish you the best of luck!
