Hi :) has anyone used these before? They say they pinpoint your 2 most fertile days but I had a smiley face on day 11 and then just empty circles since. I've had no ECWM yet either. My cycles are 30-32 days long and internet cheapies usually get dark for me around day 18-20 so this seems far too early. Is it a false positive? If it's right (I know they're supposed to be very accurate) it seems weird I had no ECWM. It says you shouldn't look at the sticks but there was a smudge of blue across it so wondering if that's a sign of a false positive. I've never actively TTC before this month, but used OPKs to avoid pregnancy. TIA!
