Depends on the individual. If you want to pinpoint an actual day for O you need to be tracking temp. When EWCM starts, and when it ends in relation to when you actually O varies a LOT depending on the person. Some people even how quickly the EWCM dries up varies by cycle.
It's difficult to pinpoint a specific day of ovulation if you're ONLY tracking CM.
