A 29-year-old woman is counseled about the Standard Days Method of natural family planning. For this method to be appropriate, her menstrual cycle length must fall within which range?

• A 24 to 28 days
• B 21 to 35 days
• C 28 to 35 days
• D 26 to 32 days ✓

Explanation

The Standard Days Method requires regular cycles between 26 and 32 days. Days 8 through 19 are considered fertile days when the couple must abstain or use a barrier method. The method uses CycleBeads to track fertile days and has a typical-use failure rate of about 12 per 100 woman-years.
