Every month is different according to my research.

Also according to the Clearblue OPK, they detect the LH surge and you ovulate between 24 to 36 hours.

Did you notice any EWCM on CD14, CD15, CD 16 or CD 17? Estrogen and LH surge are very closely related to each other. When you notice EWCM and you have a +OPK it means that you will ovulate between 1 to 3 days from that point.

Good luck!
