So far this month I've gone the longest without AF, 38 days. CM readings in the beginning were pretty usual. During fertile time I didn't really pay attention because we used pre-seed ( thank you to those who have posted about using less then what is said!!). After ovulation is where it went off as in one day dry, next day white CM, one day having EWCM (day of missed period), to heavy or medium white CM the next, to now dry. I just did pregnancy test and BFN.
