Until tomorrow morning

Beta is tomorrow at 9am - can I make it through the night?  I am hoping for a late afternoon call.  It's not a definite rule, but I think if the test is negative they call early, but if it's positive they wait for progesterone results.   

Here's hoping for a 3pm or later call.  If that "rule" is off I can also tell by the tone of the "Hi" by the nurse - one word says it all.
