"High Fertility" for 4+ days normal?

A
I've had "high fertility" for the last 4 days according to Clearblue Digital ovulation test. We've been ttc for 16 mos and this is my first time doing this    Test. Is this normal? How many days of "high fertility" do you all have before you get the Peak smiley?
