I had been trying to conceive for some time now. The other app I was using was off on my ovulation. When Glow told me I was going to ovulate (a week after the other app), I thought it was BONKERS. It said have sex because you're going to ovulate. So I did, NEXT day my ovulation stick was positive. After ONE month of Glow, we're knocked up!! I also suggest the super expensive Clearblue Ovulation Kit!
