If you lie in bed for 5 minutes before taking your BBT

Not getting up or moving, etc... would it still affect the temp?

I was so out of it this morning I forgot to take my BBT until 5 minutes after initially waking up.  But I did not move around.  However, my temp was .5 degrees higher today than yesterday.  Just curious if just lying there but being awake for 5 minutes would cause that increase.

Thanks for any help.

Yes, the waking up process will raise your temp even if you don't move around much.  I have done this a few times wondering if my temps were correct.  I temped as soon as I woke up, again directly after, and again a few minutes later without moving.  The temps steadily rose.  You really have to take it as soon as you wake up to keep consistent. 

What CD are you on? How's your CF?  I would also take these things into consideration if you're wondering if this is an O spike.  You can log that temp, but I'd mark it as disturbed so you can discard it if necessary to see your pattern better.

Thanks!  That's what I assumed but couldn't find any specifics via Google.  I'm just CD5 and AF is still here so I figured it was "disturbed."

FWIW, this is not the case for me. Just for kicks (because ttc has made me crazy!) I decided once to take my temp immediately after I woke up, a few minutes later, and after I got up to go to the bathroom and got back in bed. All three temps were virtually the same. I did this a few different days and realized for me it's not critical to take my temp the instant I'm awake. However, I know this is not the case for everyone - we're all so individual. Sounds like for you it does make a big difference, so I'd "asterisk" today's temp.

I second gozal on the timing and having virtually identical temps.  My thermometer came with a diagram of exactly where to measure on the jaw/joint area with variations by location and the average difference in temp by measuring in the wrong spot.  

That said, the left measuring point consistently measures .3 lower than the right side.
