Question 9 • 2025-2026_MDCPS_2000315_Biology_1_B-CR

When is the most likely time for a female to become pregnant during her menstrual cycle?

Answer
A
on the first day of her period
B
on the last day of her period
C
about a week after her period ends
D
about a week before her period begins

Explanation

Pregnancy is most likely around ovulation, when an ovary releases an egg. In a typical 28-day cycle, ovulation occurs about 14 days before the next period; for many people, this is roughly a week after a period ends. The timing varies with cycle length, so this is an estimate rather than a guaranteed rule.
