I'm starting to think I'm not ovulating

Courtnie • 28. Happily married. I'm a mom of Angel baby boy👼, a rainbow baby girl🌈, and my surprise pot of gold baby boy 🍀

I've been using opks and the clear blue went from low to high but no peak days. I did that for 9 days, 8 days being high. On the 10th day (today) I used first response since they are cheaper lol, and the line is very faint. I'm going crazy here. I usually follow the cm, but I tried something different this month and now I am extremely worried.

Anyone else been through this?
