I am not advising that you purchase or not purchase this monitor. I simply need to tell you of my experience if you do use it. I was very excited to find a tool that would take the human error out of reading the ovulation test sticks to determine the LH surge, therefore predicting the peak days of fertility.I used this monitor every month for over a year with one successful pregnancy (ending in miscarriage). The very thing I liked about this tool is possibly what prevented my getting pregnant sooner. I relied too much on the accuracy of the monitor! The machine reads the stick and displays the "fertile day" sign. If there are any errors in this reading, you won't know because you can't read them yourself. You must rely totally on the accuracy of the machine. Whereas, with the simpler ovulation predictor sticks, you can read them yourself; see the line to determine if it is darker or lighter than the test line and can compare it with sticks from one day to the next.
After trying to conceive for so long, I found myself only focusing on the "prime fertile days." I didn't have the energy to "try" if the monitor didn't say I had to. I think by narrowing my target to the 2 or 3 perfect days that this machine predicted, caused me to actually miss my fertile days. I think the machine was wrong. I came to this conclusion one month when I decided to check behind the monitor by using it simultaniously with the ovulation predictor sticks. The monitor read my LH surge as day 12 and I read the sticks as surging on day 18. If I had not checked behind the machine, so to speak, I would have missed my actual peak time. By NOT paying attention to the monitor readings, I persevered and kept at it until day 18 and this was the month I got pregnant.
I'd recommend that if you do buy this monitor, use it as a guideline and not as the gospel. Use it to indicate your fertile days but don't stop there. Don't just "try" on the fertile days. The one pregnancy I did have was due to "trying" even after the machine said it wasn't productive.
One final note, the sticks for this machine are bought in boxes of 30 and are very expensive. You MUST use 10 per month dictated by the machine. Purchasing the box of 5 or 7 ovulation predictor sticks is actually less expensive and you need only use the number of sticks until you see the "peak." These kits are complete as is (just add urine!) and do not require the purchase of an expensive machine.
Good luck!
