Needing help with how to accurately temp. Thanks!

J.

Most mornings when I wake up, I am very hot. I go to bed freezing so I sleep with several blankets but I am sweating in the AM. I have noticed since starting BBT charting about 5 days ago that my temp is the highest right when I wake up, almost a degree higher than any time of the day.

This morning I uncovered myself and was much cooler when I woke up to temp. It was down a entire degree from yesterday.

So I guess I am wondering if blankets and room temp effect bbt and if there is something different I should do.

Thanks!
