Tests for signs of ovulation
The best way to record and monitor body temperature is with a chart. This provides a good visual basis for determining signs of ovulation: make sure that day one on the chart is the first day of menstruation, every morning, before getting out of bed or going to the bathroom, the woman should take her temperature. A regular thermometer can be used, but special basal body thermometers should be available at the pharmacy if the woman wishes to use one. The same thermometer should be used every time, make note of any lack of sleep, drinking alcohol, fever, illness, or emotional stress. It is also helpful to describe the condition of any mucous or discharge.
Another option is a saliva test, which takes a peek at levels of estrogen in your saliva as ovulation nears. When you’re ovulating, a look at your saliva under the test’s eyepiece will reveal a microscopic pattern that resembles the leaves of a fern plant or frost on a windowpane.
