Basal Body Tempature

Basal body temperature is your temperature at rest when you wake up in the morning. This temperature rises slightly around the time of ovulation. Keeping track of this temperature and other changes such as cervical mucus may help you figure out when you are ovulating. Take your temperature before you get out of bed every morning. Since the change during ovulation is only about 1/2 degree F (1/3 degree C), you should use a sensitive thermometer such as a basal body thermometer.

Blood Alcohol Content

Blood Pressure

Blood pressure is the force of blood pushing against the walls of the arteries as your heart pumps blood. It includes two measurements. "Systolic" is your blood pressure when your heart beats while pumping blood. "Diastolic" is your blood pressure when the heart is at rest between beats. You usually see blood pressure numbers written with the systolic number above or before the diastolic number. For example, you might see 120/80.
