Question please help 😩

So i’m going to my first gynecologist appointment next Monday right, i’m 16 and my mom is taking me. I’ve had sex before but its been a year since i have, hypothetically speaking. If they found like an std or whatever who would they call me or my mom... and is it better to not shave before i go or too shave ?? Cause i’m low key freaked out about going and it’s just weird too me.
