Hello. My Name Is Nicole And I Am 15. I

Hello. My name is Nicole and I am 15. I have my first gynecology appointment next week. I have only ever had sex once, and it was indeed protected. My parents are very religious. I am so terrified that the doctor will tell my mom I am not a virgin. Can she do that? Also, does my mom HAVE to go back into the room with the doctor and I since I am 'under age'?
Thank you!
