This is my second cycle TTC, first cycle had a CP. So this Sat 3/17 I took my cheapie OPK at 9am, it was almost positive but not quite. Brushed it off, due to kinda getting fed up with obsessing over it , went on about my day. Sunday (6am) too a cheapie OPK and it was blazing positive so took my Clearblue Digital and got a smiley. So sometime between 9am Sat and 6am Sunday it turned positive, we BD Sun am-Tue. Think it was too late? Crossing fingers!!
