Late in their cycle? My temp went from 98.3 at ovulation and in that range to 98.5 and today 98.6 at 8 and 9 DPO whixh is today. Why is my temp going up now? I had to discard the temps to keep my crosshairs because I only started temping the day before ovulation and no coverline was established. I am temping internally this month. It has been very warm here the past few days do that could factor in too. Anyone have experience with this?
