My ovulation charting was going along perfectly until 4 days after ovulation, when it was supposed to revert from the transitional stage (small ferns and pebbles) to pebbles only. I'm now 10 days past ovulation and it's still doing the tiny ferns and pebbles thing. I've googled "ferning after ovulation" and it seems to be fairly common, and it's only full ferning after ovulation that could indicate pregnancy. Or a high oestrogen cycle.
