Question

Quizplus · Accepted Answer

Assuming a 28-day menstrual cycle, ovulation (when conception occurs) occurs around day 14. Counting back 14 days from March 4th gives us February 19th as the day of ovulation. Sperm can survive for up to 5 days inside the female reproductive tract, so the fertile window for this woman would be approximately February 14th to February 19th. Therefore, the approximate conception date would be 14 days after February 19th, which is March 5th. However, since it is difficult to pinpoint the exact day of conception, the closest option is March 18th.
