So I wasn't checking my CM earlier this month, but I did yesterday (likely O day) - and nothing. My last cycle was 25 days, and the one before that was 27 (still adjusting to coming off BC?) I normally have EWCM for 4 days or so before O, then the day after. I had possible mittelschmerz yesterday, so I still should've had EWCM... Anyone's body ever do this? I dunno if I O'd early, or if I'm Oing late, or what...
