Clearblue Advanced Ovulation question

This is my first time using Clearblue Advanced digital and its also the first time OPKs have ever worked for me. So I feel like a dummy.

This is Letrozole round 2 for me🙏 I'm wondering how many days you've gotten or is normal to get "high" fertility reading (blinking smiley face) ? This is day #3 for me. When should "Peak" be here?
