Which bbt?

Question

Hey y’all. I had to get up at 5am to put my son back to bed. Went back to sleep until 6ish and my temp was 97.54. Went right BACK to sleep until 8ish and my temp was 98.01. Which one would you track?

Answer

Neither. I would call it a missed temp day. 1st priority is to take your temp as soon as you wake up, regardless of time. 2nd priority is that it is at the same time. Since you didn't get the first time when you got up at 5, you missed your temp that day. The others are unreliable as you already got up and your body heat was already increasing, so you missed your basal body (resting) temp. It takes 3 or 4 hours of sleep to achieve that temp.

Answer

Neither. You need at least 3 to 4 hrs of uninterrupted sleep for your bbt to be reliable. Depending what time you normally take it, the temp when you first woke up at 5 would have been the one to record

Answer

Ok, I had that thought initially but couldn’t remember how many hours of sleep were needed. Thanks.
