I am not sure when I would consider 1DPO. I want to start testing around day 10-11 but I am not sure when day 1 would have been. Sat 8/24 I had a neg at 10:30 am then later that day at 5:30 I had a smiley. Sunday morning around 10:30 I still had a smiley ... then later that day around 8:30 it was negative. So anyone have any idea when I might have ovulated? Or what day I would consider 1DPO?
