Hi Fellow, POAS addicts. This month I got two packets of clear blue digital, started testing same day from same samples. So Friday morning circle on one and high fertility on the other, Saturday and subday High fertility on both. Monday solid smiley on one (the one with flashing smikey of Friday) LH surge cycle day 13, so Monday Tuesday solid smiley monitor out if action because it displays solid smiley for two days.
The other monitor is still displaying flashing smileys we are now on wed so two days after first solid smiley. So checked with Internet cheapie, no surge since yesterday just a line but not darker than control line. I am on day 15 today.
So which monitor could be right?
