○ You must be over 18 years old to use Natural Cycles
○ Natural Cycles does not protect against sexually transmitted infections (STIs) in any way.
○ Natural Cycles informs you whether and when you can become pregnant. Abstention or protection (e.g. condoms) are required on red days to prevent pregnancies.
○ As a birth control, Natural Cycles may be less suitable if you experience irregular menstrual cycles as predicting your fertile days becomes more difficult and you will get an increased number of red days. For birth control, it is ideally used by women with fairly regular and ovulatory menstrual cycles.
