I am of legal age and about to have a body checkup and I AM currently taking birth control pills. My parents will kill me if they know that I am taking birth control pills.

I am going to have a checkup by blood/poop/pee. Is it going to show in my blood results? WILL THE DOCTOR MENTION it when giving me the results? I cannot let my parents find out.
(( my parents will be in the room with me when the doctors tell me the results of my checkup! So i was just wondering will they mention it..or it will be irrelevant to my health therefore he won't refer to it?))
