Hi Lukesmum

It doesn't really work that way.. It tells you the days you at a high fertility and peak fertility. I however am not pregnant as i have just found out that i may have endometrios, but as i had an ultra sound around O i know the fertility monitor is right... I also have other signs that i have now recoginise becasue of the monitor, like i get major pain in my side around O. Our IVF doctor said that we should have as much "fun" around that time so i guess it doesn't matter what time of day you O as long as you have the "fun stuff" waiting. The thing I loved about the monitor is that you don't have to work out if there is 2 lines it tells you unlike the ovulation sticks it takes away the frustration... I also used a maybe Baby at the same time as the monitor just to see if it works and it was on the money as well (in sinc with the monitor). Good luck
