Does anyone else calculate their pregnancy from the day they ovulated? 
My highest 33% was on the 21st November, we bd that day and then found out I was pregnant weeks later. On the 9th December it said I conceived 1-2 week ago, which is the 25th, so very close to what glow predicted. So technically right now I'm 4 weeks not 6+5 as I initially thought. 
I had a miscarriage scare last week when I had an internal scan there was no sign of pregnancy, obviously I told the nurse I was 6+1 as I calculated it from the first day of my last period. 
And does anyone else do this?
