So ive started just temping towards end of cycle to predict when AF would arrive.i know majority of you will say i need the full month to tell anything but...im curious if you have a opinion other then that on what this dip could represent. By now my temp slowly starts to decrease,an if i have a sharp plunge like that i usually start that day an temp wouldnt shoot back up. My coverline is normally around 97.3-97.5.

Last cycle i had a miscarrage so im not 100% on when i O'd but i think im waking up to being 10-12dpo today. According to my apps AF is due the 21st. (But they all give diffrent O dates.
