No ovulation but lighter tests?!

[mindgames77]

Hi Ladies,

I normally ovulate later in the cycle...usually around cd 17 but last cycle was cycle day 26.
I started taking OPKS on cycle day 14. On CD 17 I started with EWCM which I currently am still experiencing. Yet by ovulation tests are getting MUCH lighter. I haven't ovulated yet according to my FF chart. Any thoughts?

I had tons of ewcm on cd9 and 10. I usually get a positive opk by cd12 but all negative and ewcm disappeared until cd15 with a strong positive
