Well when I was having difficulty getting pregnant, my DH went out and paid 200.00 for for a clearplan fertility monitor and guess what??? It worked, I was pregnant the very next month after using it, even though prior to getting the monitor, I had been trying for at least a year or more to get pregnant. The key to using it, is to use it twice a day, even though they say you should test with the first morning's urine. When I found out I was ovulating, I had used it in the wee hours of the morning. When the machine said I was at my peak, I woke my DH, we did the deed, 2 weeks later I took the pregnancy test even though I was not having any symptoms, and sure enough, I was pregnant. It was well worth the 200.00 investment and my beautiful 5 year old son is living proof of this.
Good Luck
