I'm 17 years old and I am planning on going to planned parenthood to get myself some birth control so I can be smart and safe when having sex. I am extremely nervous to go because I really don't want to put BC in my body because I don't want to mess with the natural nature of my body but I know that I need to unless I stop having sex. I need to know what the best choice of birth control is for a first timer and why, please tell me why I should use that birth control TY
