I have a question about birth control at planned parenthood?

Well my question is since I'll be 15 soon, I'd like to make responsible choices and Get birth control. I dont want my parents to know though. They finaly allowd me to actually have a boyfriend and I dont want them to think that just because I have the birth control its because I plan on going sex crazy. I just want to be safe and prepared you know? He's my bestfriend and... thats not important! HAHA. I just dont want them to deny me the oppurtunity. I was wondering though, since my parents dont know about the birthcontrol, will i be able to get it? Im looking for the pill, I have medicial coverage with military, but since I cant use that insurance.. trying to keep my choice hidden(please dont judge) I was wondering what my options are. How much would I have to pay? Will i not be eligible for the no insurance program? BTW i live in hawaii (oahu)
