Why Haven't They Called Me???

Last tuesday, I interviewed for an amazing job--I felt like I nailed it and that they liked me, and that they were impressed. They called me for a second interview, which was Friday September 2nd. They took me on a full tour of the facility, introduced me to the CEO, VP, and head production manager of the company- it seemed like they really enjoyed talking to me, and I felt like I nailed it again and that I was definitely getting the job (the lady talked to me about 'you guys' get this and 'you guys' get that, insurance and a bunch of other stuff!) Keep in mind: the second interview was less formal (although I dressed super business formal), and she even gave me a ride in her personal vehicle to a second facility, toured me around that facility, and introduced me to everyone there- it seemed like a lot to go through for multiple people, the total time of the second interview was 2 hours!! When we were finished, I shook her hand and she told me she would be getting in touch with me after the holiday (which was monday, labor day) and I said thank you, pretty certain that I was getting the job.

But yesterday, the the day after 'the holiday' came and went. i kept my phone on the charger all day at high volume. Nothing.

Now its already almost been a whole other day, and I still haven't received a call from her. I'm starting to get worried. End of business day is at 10 pm for them, even at corporate level...should I give them a call tomorrow if I don't hear from them at all tonight? My husband thinks I should wait till friday (one week from the second interview), but I feel the fact they haven't called me yet is a huge indication that I was not selected for the job, and i'm already so, so sad.

What should I do?????? WHY HAVENT THEY CALLED??

this job is the only thing between me not working the rest of my pregnancy and having nothing but hand me downs for my son, and being more well-to-do than we have ever been, because its an AMAZING job with great benefits and pay!!!

I already feel like such a miserable failure. I felt like the call for an interview out of nowhere was the blessing I had cried and prayed for...i traveled over an hour to get to the interview both times...and now to realize it might have been all for nothing. :'( i can't stop crying.
