I am on CD 8 and have just started producing EWCM. I am not using opks this month. Last month I had a static smiley on cd14, I believe I ovulated on cd15 as my LP seems to be 12 days now and I got my period on cd26.
Last month I started getting EWCM on cd10 and this lasted for four days, the last day being ovulation. As I said this month it's started on cd 8!
Is EWCM a good marker for fertility or is it a bit of a red herring do you think?
