Planned Parenthood?

So I'm thinking about going to planned parenthood for birth control. I currently get my birth control from Project Ruby for $20/month, but I'm looking for a cheaper option because I'm in college full time and unemployed. I'm 19, and I'm wondering if anyone here has ever been and knows how the expenses work? Online it says anywhere from free to $50, which is quite a gap. I'm also wondering if just going in and meeting with people will cost me? I have insurance, but I'm not sure what to expect. Any help would be appreciated!
