Opk question

Autumn
I have the clearblue digital it is a circle or a solid smiley. So last month this happened as well I got one day of a solid smiley then the next day nothing. So I got the postive then not even 8 hrs later nothing. Did I ovulate? I test from the last day if my period because I have always ovulated around cd 8 to 12. I am cd 11 now. I am attaching my chart too. Everything I've read out there they say you should have  few days of smileys and I hadn't since I've been using theses Thanks ?
