Premom Ovulation vs. Clearblue

Liz

I having been using Clearblue Advanced Ovulation tests the last few months with no success. I decided to try the LH strips this month too. The strips show I peaked but CB is still showing a O. Anyone experience this before and which one should I trust? I know that the strips just test LH and CB tests estrogen also but shouldn’t I at least be getting the flashy smiley?
