Due to outpatient surgery last week, I was unable to chart at the time I estimate I would have been ovulating. (Meds, dehydration, erratic sleep schedule, and general anesthesia will do that.) It is possible that the combined stress of post-holiday-back-to-work and surgery prep delayed my ovulation.
However, since Saturday, I've been getting waking temps of 97.2F and 97.3F. I realize that may not be terribly high in the grand scheme of things, but in roughly 4 years of charting (4 months now and 3.5 years several years ago), I've pretty much always had coverlines in the 96.8F to 97.1F range. I'm certainly not discounting the possibility of a one-time anomaly (meaning I may not have ovulated yet), but it really would have to be a sharp departure from my norm (at least my historical norm, which is more firmly established) for that to be happening.
About how consistent are your coverlines from cycle to cycle?
