Clearblue Advanced

Renee

So my question is has anyone used the clearblue advanced ovulation test and recieved high fertility and not peak fertility test, and then the test turn negative? I am on CD17 and have got high fertility smiley the past 8 days but no peak? So if I have no peak or missed it will the test turn back negative or will it continue to display the flashing smiley every time I test? I have never had this happen before and its seriously driving me crazy!!
