How does it affect your chart? I slept like poo last night and certainly not 3 hours in a row. Right when I need to see if I am Oing too.

(Think I might have missed my LH surge but not sure.)
I woke up to temp anyway and I got a temp within one minute, which never happens. I got 97.18. It usually takes 5 minutes or more.
So I took another temp immediately and got 97.82.
Which one should I put in my chart?
