OPK- waiting.....

Dina
Second month of trying. Cycles are somewhat normal between 26-30 days. Last month got a flashing smiley face the day after my period, but no peak day. This month not so much. Been testing since Monday (period ended Sunday) and still coming in low. 
In my fertile window per glow and Ovia so we will see...I read on the box to take the test first thing in the morning but now i am seeing comments that maybe I should do it in the afternoon or right before bed. Anyone have any insight? 
AF due August 2- hoping we are successful this month.
