EWCM Only One Day
Fertility Awareness
Obie Editorial Team
A: If you observe EWCM only on one day, and it's at the right time, then it's likely that ovulation happens within a day or so of the EWCM. But because many women with EWCM don't ovulate exactly at the time of EWCM, and many fertile women who ovulate don't necessarily have EWCM, you can't use EWCM exclusively as an indication of ovulation.
