Not ovulating

[HopefulHarry]

Hi everyone. I have been ttc for 10 months now. I currently use the clear blue advanced ovulation kit. I have been testing since cd9 and I keep getting a blank circle. I am on cd12 and still no smiley face. In previous months of testing I normally get a flashing smiley face between cd10 and cd12.
I'm beginning to think either I have not ovulated, ovulated early or going to ovulate alot later than expected. Anyone had any similar experience or cam shed some light as to what is happening?

Hi - on my 1st month using the CB advanced OPKs, I got 2 days of nothing and then 7 days of flashing smileys before I got my static. This month, 2nd month of using them, I had 6 days of nothing and then straight to static smiley, with no flashing smileys at all! So don't lose hope/panic yet as I think by all accounts, it can be quite variable. Good luck
