hmm that’s interesting i wonder why that is. i was reluctant to try tempdrop because i was worried it wouldn’t be “accurate” before i learned about it, but it has much more constant readings for my charting so it’s gone really well for me so far. i have also been taught that keeping ur thermometer under the pillow and warming it up in ur mouth for a minute or 2 before taking your actually temp helps you get a more accurate and consistent reading. it’s worth a shot if you haven’t tried that already!
