How much do you find time difference affects temps?

[SallyJ]

I am wondering how much people find taking their temp at a different time affects their temps. For example, taking it an hour earlier or later due to circumstances?

My DS woke me an hour early this morning and am wondering what my temp could be if taken on waking at the usual time.

I took it at 5am and it was only 36.85, but I've taken it now at the usual time (admittedly after I've already got up, but I haven't moved around a lot) and it's 37.1. Should I average them out? Can I use the 2nd one?
