I started af on the exact cd for last 3 months so my cycle is regular. Why did I go from 96.99 the day before af to a steady 97.7 the last three days during af? I thought my temp should have dropped during af not rose 0.7 degrees? I was on antibiotics for kidney infection from cd7-17 so I assumed that is why I didnt o and had very jagged chart but am perplexed by the huge temp spike now.
