Title says it all really, I'm on CD11 of an average 30 day cycle and I suspect I OV somewhere near CD16. I've just started using the CBFM as we've been trying since a MC at Christmas with no success. So I guess my question is despite the abundant 3 days of EWCM can I trust the CBFM saying i'm not likely to be fertile at present? I usually get lots of EWCM before, during, after OV and immediately before my period hence my confusion over when I OV.
Naturally I'm going by the mantra of having lots of sex when EWCM appears but I'm just a confused and curious CBFM newbie.
Any insight gratefully appreciated!
