My first birth control?

Erin • UC nursing
I've been looking into birth control ever since I was 16 and I'm turning 18 next Saturday still relying on the withdrawal.. 
My pediatrician told me NuvaRing was a good choice because of her information on what she found would be best for me, but after reading forums on it I still am not 100% for it. 
The pill on the other hand just seems like something that more girls go with, but  my issue with picking a bc is safety!! I do not want to mess up my insides! 
Which birth control is a better plan for me to use since I will be adding hormones to my body for the first time?
