Research Facts
Basal body temperature thermometers are marketed and sold specifically for women trying to get pregnant. While charting your basal body temperature (BBT) is a good way to track ovulation, one of the biggest benefits to this method is the low expense.
To get an accurate reading, you must take your temperature when you first wake up in the morning, before you even sit up in bed. And you'll need to use a basal thermometer, which is sensitive enough to measure minute changes in body temperature. Try to wake up and take a reading at about the same time each morning.
