Prepare for Appointments?

I have my first appointment tomorrow and I'm a mess. I just spent forever in the shower literally shaving my entire body lol. I'm so nervous they are going to do a Pap smear or a vaginal ultrasound. I haven't been to the Doctor in years but I'm always nervous that I smell or my body is weird and I'm going to be one of the patients he talks about to people. I'll be wearing my good underwear for sure tomorrow ?
