This is my 1st cycle using the clear blue dual hormone sticks, day 27 now. I only have 4 sticks left out of 20, I've had 8 days of flashing smiley faces now. Has anyone else had this and finally got a fixed face?
My record was 13 days of flashing smileys. Ran out of sticks for a two month pack. Swapped to the Internet cheapie OneStep OPK sticks and returned to peeing on them in the afternoon rather than FMU. Caught the surge and BFP!
At the time, I emailed ClearBlue and they said that the oestrogen surge has been caught but as the LH surge has not it been caught, the holder will still show flashing smileys - even if ovulation has been and gone. It is worth noting that their advertising has since changed from "Will show your 4 most fertile days" to "Will show your 4 or more most fertile days" or similar.
I had 12 days of flashing faces and then ran out of sticks but on day 13/14 had ewcm so assumed I ovulated then. I used cheapies in the afternoon and still never got a surge even with ewcm present. Having now read the packaging and seen that it says not suitable for PCOS so if AF does arrive I won't be buying them again.
