I regulary check my fertile days every month using the clarblue advance digital ouvulation sticks since my mmc in march. This month i came on my AF one day ealier and was due my flashy smiley on sunday. The date came had a blank circle, monday i tested and got a static smiley, im slightly confused. Thought id test again this morning and blank circle. I usually get a flashy smiley on monday and tuesday a week before the end of the month and have done since july. Is this normal, im planning for my rainbow baby.
