I had asked on here if anyone has used this and it seemed like most hadn't even heard of it. Well, it's kind of expensive, but it told me I was ovulating today! I'm so excited, and I love this monitor- no guessing or worrying and it's fun to watch it light up bright pink when it's time to BD! Highly recommend this product, I thought I ovulated much later in my cycle, I'm on CD 11. Hopefully this will finally be our month, if not he's getting a SA, no more excuses!
