worried

So I was late for AF on Saturday I took 3 test and I got two positives and a false(digital) so I know digital need more HCG so I though yay I'm pregnant well now I'm double guess everything I took another test and I didn't seem any darker shouldn't be getting darker on top of that my OB says to wait until I get a positive with the digital test before I can make an appointment but they want me to test again this weekend and call them back ambi worrying over nothing or what??? I want this so bad and I'm never late
