Birth Control

So I’ve been with my boyfriend for almost 10 months and I’m 17 and really in love with him. He respects me and my readiness for sex but he is ready whenever I am. Next weekend my parents are going to a concert and I will have the house to myself for the night. I want to have sex with him and I think I’m ready. I am SUPER paranoid about getting pregnant. I haven’t ever tried birth control or anything but I feel like just a condom isn’t safe enough. Is it possible I can get birth control without parental consent? Or should ai just trust the condom?
