Has anyone experienced blank circle to straight solid smiley on the digital clearblue advanced OPK? I thought it was supposed to detect the rise and I’ll have blinking smiley before the solid one...

The past two cycles I ovulated CD16/17 and I’m only CD10 today. I didn’t believe my morning’s clearblue digital opk so below is my internet cheapie OPK that I just took...guess I will be ovulating early this cycle. Thoughts?
