OPK test strips -Confused

Jehnna

I would love to see your OPKs for a month to compare to mine. I know everyone is different but this is my first time using them and I’m very confused.

I also used clear blue and got my first solid smiley face on cd 21. I’m confused as to why I got a blazing positive strip but negative CB on cd 23?

I also know that I ovulated somewhere from cd 20-22 but I think It was cd 21 bc of my pains I had, so any help is appreciated!
