High cover line?

[squirrel.]

Hi ladies,

Just curious about my cover line on my FF chart. It's way higher than normal. How are they calculated? Isn't it an average of pre-o temps? It doesn't seem to be as it's in line with my three highest temps and then 17 temps well below it.

Not a problem, just curiosity.

I dont think every months chart is the same...could be a bit off from the month before. You chart looks good though. I just started this cycle and was doing pretty well taking the same time everyday...but then wouldnt you know, around O time I start waking up in the middle of the night and screwing the whole thing up!
