1st gyno appt and scars

Help. So tomorrow I'm going to my first gynecologist appointment. I'm really freaking out because I have some recent cut marks on my hips and I know the doc is gonna see them. Will he tell my mom if he does? Like is he required to say something to her about it? Because if he does then my parents will punish me for it like they used to and I can't go through that again.
