Tons of EWCM last night and when I woke up this morning. Ovulation test strip not even close to positive. Usually the line on the OPK gets darker each day approaching ovulation but the line is still so faint. I'm on CD 13 and usually ovulate anywhere between CD 14 and CD 19. How long before ovulation can EWCM appear? Usually for me they coincide with each other but apparently not this time. Think I'm still close to O even though test is quite negative?
