TTC: Cycle 1 - 3 or 4 DPO?

Cycle Day 37

This morning I had a really high basal body temp reading, 98.64 degrees.  That's the highest it's ever been.  I went to add the number to the Fertility Friend app I use for charting my BBT and it finally added in my red line cross hairs that is supposed to pinpoint my exact ovulation day based on my other data I've been inputting (cm, OPK results, temps, ect.).  

Based on it's estimation I ovulated on Friday, July 20th.  So it is saying I am 3 DPO today (which I thought a negative OPK = no ovulation and would put me at 4 DPO).

So I think to be safe, I'll go with their prediction and say I am 3 DPO today!  Which again, changes my calendar... but I will leave that because no one knows exactly when these things happen.  I will still probably test on Monday, July 30th for the first time which will be 10DPO and I am comfortable with taking a test that early.

Here's my full calendar from Fertility Friend:

 We did BD during my fertile window, but not after, so fingers crossed!!!

One week and counting...
