On which days is intercourse avoided with the calendar method?

Question

Quizplus · Accepted Answer

The calendar method involves avoiding intercourse on days 10-17 of the menstrual cycle, as this is the time window during which ovulation is most likely to occur. Days 1-9 and 18-28 are considered less fertile, although not completely infertile, and therefore do not require as strict of avoidance measures. Days 5-14 and 15-22 are in the general vicinity of the most fertile window, but do not encapsulate it as precisely as days 10-17.
