clearblue?

So last night I came home from work early...about 1145pm and slept til 0430am when I woke up I took a test (clearblue digital) and it was positive! 
No error message (the lil book in the corner) like once before which indicates "error". I was so excited we went to the store about a hr and half later and got First Response and it read negative. Took another around lunch...another negative. I have to work to night so I just slept 4 hrs and took another...another negative....could it be that it's not "morning pee"??? bc my period it's due til Sunday....too early???? Using Clearblue I hear they give a lot to false positives???? 
Help! 
Uploaded pics...thought maybe there was a VERY faint line in the 430pm one but I could be wishful seeing... :)
