Stretchy clear EWCM four days after DTD - too late?

[stillfrazzled]

Got stretchy threads of clear CM this morning - not completely slippery yet, but defo stretching to an inch or more.

We last did the deed on Sat night. Have I missed the conception window, do you think?

Dammit, forgot to mention am CD14. No ov symbol on my Persona, though.

Must remember to use the Preview button in future!

Can't - DH out!

Am sort of trying the pre-ovulation for a girl idea out anyway (is our first month, we have a 2yo DS).

OK, this is weird. By mid-afternoon, CM had gone cloudy and less stretchy again.

Did I really have a fertile window of three hours?

Or did I just possibly conceive and body knows no need for the stuff?

Exposing ignorance here, I suspect!
