I failed my 1 hour with a 140, and just passed the 3 hour today. Several of my friends and coworkers have said the same thing happened with them. I actually seems like more people failed the 1 hr than passed it (at least in the group of people I spoke with).
I have also seen many women on The Bump say the same thing. . . so I am sure you will get lots of replies.
Try not to worry. Chances are good that you will pass the 3 hour. Even if you don't, it just means you get to eat super healthy for the rest of your pregnancy :)
