Clearblue digital opk

Courtnie • 28. Happily married. I'm a mom of Angel baby boy👼, a rainbow baby girl🌈, and my surprise pot of gold baby boy 🍀
This is my first month using opks. I have been getting my flashing smiley face (high fertility) for 7 days now. I haven't had the solid face yet (peak fertility ) is that weird? I'm not sure how long they are supposed to last for. Now I'm getting worried that I'm not ovulating.
