History / How it works:

Although the rhythm method can work for some couples, the human body and its cycles can be unpredictable. This method operates on the premise of predicting ovulation by charting the woman’s temperature at a certain time daily over several menstrual cycles and/or analyzing cervical mucus quality and thickness. Intercourse is then avoided around the time of predicted ovulation.

You may need to see your doctor or buy a book on the subject to effectively use this method.
