Evening pos opk

Hi! I used the Clearblue brand ovulation tests last month that only showed peak (smiley) or low (circle). The day I had my peak- it was a circle that morning and then a smiley that evening. I ended up with a bfn so this month I’m using Clearblue Advanced with the flashing smiley included. This morning (again) was a circle but this evening it’s now flashing. Am I maybe not testing at the right time? Glad I’m doing 2 a day or I’d be missing these! Anyone else have the evening peak and got a bfp?
