Planned parenthood..

Hey guys, so the condom broke, but he didn't cum yet and we just switched one out, but I'm still worried. I want to get emergency contraception just in case. It's around $50 at my local cvs, but I really don't want to spend that much. I've heard I can get it for free at planned parenthood?? But if I do that I'm pretty sure I'll have to put in all my tax information and my insurance and how many people live in my house, etc. I live with my parents and I don't want to have this on insurance because I know that they will see it on the insurance overview at some point. Would I get in trouble for saying I don't have insurance and I live alone at planned parenthood? How do I go about doing this?
