A couple uses the Standard Days Method for natural family planning. The woman has regular menstrual cycles of 28 days. Which days of her cycle are considered the fertile window when they should avoid unprotected intercourse?

• A Days 1-7 of the cycle
• B Days 14-21 of the cycle
• C Days 10-17 of the cycle
• D Days 8-19 of the cycle ✓

Explanation

The Standard Days Method identifies days 8 through 19 as the fertile window for women with cycles between 26 and 32 days. This accounts for sperm survival (up to 5 days) and ovum viability (12-24 hours). The method uses CycleBeads to help track these days.
