Review on Clearblue Advanced Digital Ovulation Test Kit (20 Sticks) by Amanda Castillo

My average cycle is 29 days. But I could not get accurate results on disc 9 and 10 due to abuse. I really thought these tests were junkies as many reviews on these Clearblue Advanced Fertility Tests are inconclusive. Then I got blank smileys CD 11, 12, 13, 14, 15, 16 for 6 days in a row. On CD 17,18,19 I flashed emoticons for 3 days in a row. And today, April 5th, I got the Unblinking Smiley on the 20th disc. I haven't had any positive ovulation results from the test strips this cycle. I've been using test strips for over a year. I still can't get pregnant. So I thought trying it and I have a positive ovulation result. And since he says he predicts about 4 days or more fertility, I got 4 days fertility. I ordered 2 tests with 10 pieces. But the second holder is defective. So, even though I've had fertile days, I'm giving it 4 stars.
