At 6:20, after you temped, did you get out of bed (go to the bathroom?) at any time before taking your temp again at your normal time?
If you did NOT get out of bed I would use the SECOND time.
If you DID get out of bed I would use the FIRST time. (Since your blood got flowing from moving around)
My temp went down a little this morning but I also woke up at an unnormal hour to get in some extra time at work. I marked it as such on my chart.
CHEERING YOU ON! Good luck on getting your blood test back today!
