I've been charting for about 6 months this time around, recording CM (not temps, as I never get a solid sleep anyway - so I don't know how reliable it would be!)

I always seem to O sometime around day 17-19, then AF around day 30. Because I don't get fertile CM until later in the cycle, I tend not to bother checking until around day 12??

But last month, I didn't have any fertile CM & I wonder if I O'ed early (maybe at day 10-ish?). Then I got AF earlier than normal (at 26 days).

Then this month, I have had watery CM for 3 days (days 8-10) & EWCM today (day 11). Today I have also had some pinky streaks in EWCM (which I know can be from ovulation). If I was not pregnant, would AF come early again?

So, my question is, when there are fluctations in your cycle, does your luteal phase change? or follicular phase? or do they both change??
