How many days after ovulation does menstruation typically begin?

Menstruation typically begins around 14 days after ovulation due to the regular hormonal cycle in a woman's body. This period is known as the luteal phase, which lasts approximately 12 to 14 days in a standard menstrual cycle. If pregnancy does not occur, the levels of hormones such as progesterone will decrease, leading to the shedding of the uterine lining and the onset of menstruation. This timing is consistent across the majority of menstrual cycles, which generally last about 28 days, placing ovulation roughly midway through the cycle, around day 14. By understanding this cycle, it becomes clear why the correct answer aligns with the typical physiological processes involved.
