The waiting game

I made my first doctor's appointment, but it isn't until July 26.  I understand from all of my reading on the Internet so far that doctors don't want to see you until you are at least 8 weeks pregnant.  But what are you supposed to do until then???  How do I know everything is okay in there?  It is tough not knowing anything when it is happening inside you!  I am going to take another home pregnancy test this weekend just to make sure things are still okay.  Does that make me sound paranoid?  Oh well!
