i usually take my BBT at 7.30 or a few minutes before but today woke at 7am and took it a few minutes later just to see what it was. I lay in bed until 7.25 and took it again, there was a considerable difference. I hadn't moved or dunk anything in that 20 minutes. What's best to use the first or the later??
also as an aside i've done an experiment before where i took temp at usual time, got up to go to the loo and went back to bed , checked it again and it was exactly the same- weird how it can fluctuate sometimes so wildly and other times not!!
