I am using the advanced clear blue easy OPK’s which give you a 4 day fertile window. I’m currently on CD14 and got a flashing smiley!! my excitement is now turning to nerves, because the shortest cycle I’ve had in a year was 35 days, longest (last month) was 48 days, and my average is 39 days. So this seems really really early if it’s true that I will now ovulate around CD18. with these tests, once you get a positive you can’t reuse them so I’m nervous this doesn’t make any sense and I will miss my real FW later this month because the test screwed up! Has anybody had any experience with this?
