Not every rise in temperature indicates a thermal shift. A temperature disturbance is a false temperature rise due to causes other than ovulation. Factors that can disturb the temperature should always be noted in the chart and a disturbed temperature is marked with a circle and discounted when interpreting the temperature chart.

Causes of a disturbance of the Temperature (Basal Body Temperature, BBT):

  • Taking the temperature at a different time that usual.
  • Taking the temperature in a different orifice that usual.
  • Using a different thermometer.
  • Alcohol intake the night before.
  • A Disturbed night.
  • Sleeplessness
  • Fever due to illness.
  • Travel/ Holidays
  • Stress
  • Emotional upsets
  • Medication
  • Heavy meal before sleeping
