Trying not to go crazy 2ww SUCK!!

K
So, I'm trying not to go crazy during the 2ww! But I'm curious- have you ever kept OPK testing after peak fertility? Just to be curious, I did. 
Using Clear Blue Digital Advanced, I started testing:
CD 14- low fertility
CD 15- low fertility - baby danced away the afternoon!! 
CD 16- peak fertility (I guess I skipped high fertility timing) baby danced twice, mid day and late night. 
So with CBDA, the smily face stays positive for 2 days. 
I kept testing on the strips and using the application when the ☺️ disappeared. The lines got lighter but still very apparent, when I started using the applicator with it, I got a low fertility on CD 19 I got a low fertility. CD 20 and now 21, the applicator now is showing a blinking ☺️, which is high fertility. Why would I still get two blue lines on the stick and a blinking smiley? 
Just wondering what your thoughts are. 
I'm hoping we did the baby dance on the right days to get a BFP in July! 🙈👶✨
