BBT Question

After ovulating, do the 3 consecutive rises need to be higher each rise? Or as long as it’s much higher than the lowest point of ovulating, then it’s fine?

Like if 96.5 was the low point of ovulation. Can you still have ovulated if the next point was 97.33, down to 97.10 then back up again? Or does that one tiny drop mean no ovulation?

Basically, does a .23 degree decrease during the 3 consecutive rises..completely rule out ovulation?
