Hi all, I have a quick question. I don't think I've ever discarded a temp, but I'm wondering if I should today, opinions please. Yesterday we had over a 20 degree temperature drop outside from the day before, so me loving cooler temperatures slept with windows open. We woke up to the house being 64 degrees instead of 73 like it has been. Brrrrr! Do you think this would account for an almost 1 degree drop in bbt? Should I discard and see what happens tomorrow? TIA!
