Help?!?

Arielle
Ok so I'm 17 and im turning 18 soon, I was on birth control pills but a while ago my boyfriend( of 3 years) and I put a pause on having sex and when it came time to refill my birth control I didn't because I didn't see the need to. My mom knows I was on birth control but doesn't know i have stop taking it and I don't want her to know. 
But because i am turning 18 I have to switch from my pediatrician to a regular adult doctor; I am scared that the doctor will be able to see I haven't refilled it and tell my mom. 
Please Help, I don't want my mom to find out. Will my doctor be able to tell I haven't refilled my birth control??
