So I'm on CD14 currently. In the past I haven't ovulated till CD18 or 19 (typical 33 day cycle). This morning for some reason I was SUPER tired and woke up 2 hours later than I normally do, this never happens. My temp has been steady around 97.33 but this morning was 97.86. I also took a clearblue advanced digital and it showed low. Do you think the temp spike was just because I woke up 2 hours later than when I usually temp?? On here it says my fertile window starts tomorrow and I just started the ovulation tests today. Should I just consider this temp an outlier?
