This one's a bit intriguing. If the normal menstrual cycle is 28 days, starting with beginning of menstruation as shown in chart, then ovulation is at day 14. For the question, they're saying that a woman's normal cycle is 20-24 days instead of the 28. Why wouldn't her predicted ovulation also be at the midpoint between day 1 and day 20/24, in other words days 10-12?
