A fertility monitor (with the most popular being the ClearBlue Easy Fertility Monitor) uses two hormones (luteinizing hormone and estrogen) to determine when you are most fertile.
The monitor will show you the best days to try and conceive by indicating your low, high, and peak fertility days.
It's more expensive than other ovulation predictor kits, but has an excellent reputation and is recommended by doctors and Ob/Gyn's.
