When did I O?

Hello experts ! Just curious on your opinion. I usually get a positive opk around cd17, tho my cycles are irregular.
This month on CD 13 i noticed EWCM and also cd14.
I kept buggering up my opk tests so only tested on CD 15 at which point it was a peak non flashing smiley.
My cm was noticeably non existent this day though.
When do you think I o’d??
Thanks!

I can't tell from any of that, I'm sorry.

But it IS totally poss to O earlier even if you normally O CD 17.

But also possible to have EWCM many days in advance of O.
