What do I do???

Okay, so me and my boyfriend have been dating for over a year and we are in love with each other. We both really want to have sex, but I told him I wouldn't do it unless I got on the pill somehow Bc I feel that condoms are not safe protection against pregnancy by themselves. The only think is that I'm still under 18 and my parents are against pre marital sex 110% and would never allow me on birth control. So basically, is there anyway I can get birth control without my parents knowing? Or should i just trust that condoms by themselves are safe?
