Is this my peak?

BB

I got a static smiley on the Clearblue digital OPK, but it went away when I ejected the strip. I used these to get pregnant with my daughter four years ago, so I remember the smiley is supposed to stick around. Was it just a defective test? Paired with this morning’s wondfo test, I’m thinking I did hit my peak today, but I’m new to these kinds of tests. Any ideas? Thank you!
