My period waa supposed to be here the 10th of July . Its now ,July 14 I took a 2 clearblue test ( advertised : 5 days earlier from.missed period) , it waz the digital and it said not pregnant . Then today this morning after 3 more days I took another one and it said not pregnant too . Im 15 I know that's way to young. But I think I'm being paranoid. I need adult help.

You're only 15, so it's quite possible the reason you're late is that your periods aren't regular yet... especially if you only got your first period in the last year or two. You're right... you do need adult help... you should talk to a parent. I would suggest you start the conversation by asking for birth control!
