My first gynecologist appointment

Ok so I may sound so dumb for asking this, but I just want to know. Ok so I want to make my first gynecologist appointment soon since I have such bad periods so I want to get on the pill but I know you have to go to the gynecologist office first. But the thing is. I don’t even know what it’s like at the gynecologist. I know you do a Pap smear and stuff. But i don’t know what that is. Or what it’s like at all. I just want to know what to expect when I go so I can prepare myself. I know I shouldn’t be worried since you have to go to one throughout your life and they’re not scary, but I still would like to know what goes on when I go.
