A normal menstrual cycle lasts how many days?

Explanation:
The cycle length is typically taught as about four weeks, counted from the first day of a period to the day before the next period starts. A 28-day cycle is the standard reference length because ovulation tends to occur around day 14 in this pattern, giving a predictable hormonal rhythm. While there is normal variation and many individuals have cycles shorter or longer, the most representative and commonly cited length is 28 days. Among the given options, 28 days best reflects the classic, widely taught value. Shorter or longer options can occur in real life, but 28 days sits at the center of the traditional teaching.
