Opk testing

Share your opk stories. What tests do you use? When do you start testing? Is peeing on a stick getting to you? 
This month, I got a flashing smiley ( using clear blue advance) earlier than glow predicted and it's still flashing x4 days!!!! It hasn't done that before. Is that normal? When's the big O coming??? I think the opk are stressing me out. 😫🔫
