Weird clearblue test....

So this Moring I took a normal test and thought I could see a second line so I took a digital clear blue and it said pregnant, I then set it down and if fell off the counter and it changed to not pregnant and that freaked me out so I took a second one and it said not pregnant I took the first one put the batter back in it and it changed back to pregnant but now I am confused, as to what to believe, I now have a test with two line one weird digital test that says pregnant and one that says not its 4 days early so I have more time to get a better positive but I'm still confused.
