Hmmm, you usually O on CD17 and CD18 (from your overlay chart) and on two other cycles it shows you O'd on CD23 and CD26. Just to be on the safe side, I think you have to BD on alternate days until day CD26. Since today is CD20, you only need 3 more days of BD'ing.

Actually, even 2 days of BD would be considered good, since we have seen cases where the coupld BD 4 days before O and got pregnant. It depends on how well the boys stay alive in there. You didn't write down your CM today, is it still watery/EWCM? If it is still fertile CM, then I think you haven't O yet, but FF has also mentioned that ppl do get EWCM even after ovulation, from the leftover of the corpus luteum. But in your chart, I don't see a clear temp shift yet, so continue BD'ing.

Today's temp of ~ 96.7 is on the low side (lower than your coverline last month).
I hope you'll get a temp spike in the next 3 days. I'll be rooting for ya!
