Not so patiently waiting...

So after a couple of days of high 99, low 100 temps she is back down to mid 98's, latest temp is 98.3!!  Question is- has she just dropped back to where she was or is this a legitimate pre-whelp drop? Last night she was so restless and couldn't sit still and when she did lay down she would have to rock back and forth to get some momentum and get back up! She goes back in to the vet in the morning to be worked up again, to avoid an emergency over the long weekend.  I'm highly doubtful that she'd last until Tuesday at this point so hopefully her levels are low enough that they can do the C-section tomorrow!
