I can feel my tampon in me?

I swear I have tried like fifty million times! Yet I can always feel it :( I know it may be because it isn't in far enough and yes I know your vagina is actually pretty big and that it can't get lost in you. But I can always feel it! When I am sitting down, when I am standing any position i can always feel it. And hurts like a bytch taking it out! HELP PLEASE, cause I am going to a pool party in like literally half an hour...
