If you decide to track the changes in your body that occur with ovulation, you will need a thermometer. Experts say that it is best to use a basal thermometer for basal body temperature (BBT) monitoring because it is more precise and measures a smaller range of temperatures. Users like the BD Basal Digital Thermometer because it has a large, lighted digital display that is easy to read, especially in the darkness of your bedroom. The thermometer also beeps to let you know that it is working, but some find the noise disruptive to their sleeping partner. A drawback to all BBT thermometers is that you need a consistent sleep schedule, must measure your temperature around the same time, and know that any illness or excessive movement can affect the results. Also, the temperature spike occurs after ovulation has occurred, so by itself it cannot predict ovulation. If your sleep patterns are more erratic, reviewers say you should consider a urinary ovulation test such as the Clearblue Easy Ovulation Test Pack (*Est. $21 for 7 tests).
