First gyno appointment.................?

I am 21 and I'm having my first gyno appointment tomorrow. I know it's a bit later than you are supposed to go, but I wasn't sexually active until recently and didn't have any problems either. It probably sounds stupid, but I am really nervous. This nervousness is what has held me back from going for so long. So what is a first gyno appointment like, and what can I do to be less nervous?
