My bbt was around 97.92 and started dropping when af was supposed to arrive. It hovered around 97.72, one day was 97.36, during af but shot back up the last two days to 97.92 again. Last month after af my temps where around 97.34. Today is the first day with no af, why are my temps so high. Has anyone else experienced that? I had normal period so know I'm not pregnant.
