clear blue advanced ovulation test

Kim
Hi,
Has anyone had issues with clear blue advanced ovulation tests? I started taking them last Tuesday 9/21 CD 11 and it showed low until Saturday 9/24 CD 14 when I saw that flashing smiley. It hasn't peaked yet. I've taken it every morning with my fmu and nothing has peaked. It's still shows high every day. I'm getting discourage that I won't ovulate this cycle. Has anyone else had issues with it not showing their peak. Is it possible at day CD 22 I still haven't peaked?!
