Ovulation Question.

I have had a blinking smiley face on the Clearblue Advanced opk for 6 days but the lines are no where close to looking the same. The first line is super super light. Is this normal? The lines don’t look like they are getting any darker either. My period never came last month and I keep getting bfn. I went to the doctors and got blood work done and currently waiting for the results. I went off the day I was suppose to get my period so I believe I’m on CD 16 ( af is 16 days late) Is it possible that I will still ovulate this month?
