Can late-cycle ferning be a sign of PG?

[AnyDream]

Hello, Got an awful shock this morning when, after 10 days of post-ovulation pebbles in Maybe Baby, there was ferning again :eek: !! Am on CD 22 but think I O'd early making it probably a 25 day cycle.

Does anyone know if this sort of late cycle ferning might indicate pregnancy? I'm thinking both oestrogen as well as progesterone increase in PG (accounting for most of the early symptoms). Either that or maybe I didn't O at all the first time and my body's having another shot.

Any thoughts?
:-)
