Help me out?

So, I was born a guy, but I've always been feminine. The thing is, I go between times where I feel more masculine, where i prefer to be referred to as a guy, and times where i feel really feminine, and at those times i much prefer to be referred to as a girl, and the way i act differs too. When i feel more feminine i also feel like dressing differently as well. I want to know what you guys would consider this, I'm still new to this stuff and don't know a whole lot about it so I'm sorry in advance, would this be considered something like genderfluid? Id really like to know as I'm pretty ignorant about this stuff
