Brysonsmommy--I have been using the fertility monitor, and it is awesome! I am irregular also, so it's great to see the monitor go from low to high to peak. Once I get the "high" reading, the

begins! Fortunately, I got mine from my friend so I didn't have to shell out the money for it, but I have gone through 2 boxes of sticks. The first couple of months I wasn't too sure about it, I was getting crazy readings and no peaks, but I think it still had my friend's info in it's memory, so it needed to get used to me. I have gotten three peaks the last few months, and this cycle I ran out of sticks before I got a peak, so I went to the $store and bought some cheapie ov sticks to finish off the cycle. I hope it works so I won't have to buy another box!! I have heard you can buy them on e-bay used and cheap--just be prepared for it to take a couple of months to get used to you. I have always been concerned that since I am irregular I may not be ovulating, but with the monitor, I see that I really am!!
Good Luck!
