I'm confused

Okay so my boyfriend and I want to have sex, but I keep holding out (not because I'm not ready or don't want to) because I want to be on the pill. I'm 20, but still live with my parents because college is expensive. My parents would not approve of me getting the pill. I was reading about getting the pill from Planned Parenthood without insurance and simply showing them a pay stub or something? But I'm confused on how all of this works. Is it possible for me to get the pill without my parents knowing, without insurance, and just with a pay stub and whatever else?
