Late period and high fertility on CB advanced

I originally had a “peak” reading on Clear blue advanced opk on cycle day 14.

Today I’m on cycle day 36 and have had several negative pregnancy tests. My period is two days late.

I took a clear blue advanced opk test and it read “high fertility.”

Does this mean I didn’t ovulate earlier in the month and I’m getting ready to ovulate now?

Anyone had this happen?
