If you were to go by temps alone I would agree with FF... but there is that seed of doubt put in my head b/c of your FM reading which made me re-think my 1st glace at your 2 charts.

I think I would side with your FM. A normal LP is 14 days, your last chart would have a 14 LP if you bumped your O day last cy to CD#18 which would be on your 1st P. If we take that change of O day as fact for your last cy, this chart and last would have those 2 days of lower temps right after O (CD# 19 & 20 & CD# 18 & 19 this cy) before it shot up making the 2 charts quite similar.

This O day change would work with your FM readings and it's not crazy to think your temps could be slow to rise after O.

If you do change, be conservitave with pg tests and do keep in mind that ther is a chance you could be ahead a couple of days.

HTH! And good luck this cy!
