Hi guys, just looking for a bit of advice if that's ok. I had a poor nights sleep last night, then woke at 5.08am, took my bbt which was 36.54, dozed but didn't get up or move or anything, stupidly took it again at normal time of 05.40 (shift worker so even on days off i wake at this time but can go back to sleep) and it was 36.71. which temp do I use? bit confused........
