Ovulation Kit

Has any one used the Clear Blue Advance Ovulation Kit? I liked the concept that it will let me know when I'm low, or high fertility or when I'm at peak fertility. This is my first time using this and it said you usually have high fertility 2 days then ovulation will occur and you will reach your peak fertility.

You get 10 sticks and the first 2 days it said low fertility. Now I'm on my 5th day of high fertility but I have yet to see the peak fertility. Is this normal? I'm so confused. Hopefully some time within these next 3 days I will get a peak! Crossing my fingers and confused at the same time.

Anyone been through this?
