Doctor check up help?!?

Ok so this wensday im going to have a doctors checkup im 13 btw. So it's a pedestrian. (however u spell it) I no what they do and stuff and they usually take a peek "down there" to check if u have pubic hair growing and such but i shavee so will they ask and stuf and usally its kinda stubby and has lil cuts since i srrrsly need to get a new razor. This will be pretty embarring if they do tht and c and my mom will be in the room and the doctor is a girl my mom said, so if she asks do u shave or something and i dont exactly want my mom knowing tht since she shares everrrything with my dad. I think its personal and its un fair for them to do so. Any suggestions?
