When do premenstrual distress symptoms typically peak?

• A. 4 to 7 days after menses.
• B. On the day of menses.
• C. 4 to 7 days prior to menses.
• D. 2 weeks after menses.

Answer: (C)

Premenstrual distress symptoms peak during the luteal phase, after ovulation, when hormone levels are fluctuating and then fall just before bleeding begins. This leads to a symptom flare that commonly reaches its highest intensity about 4 to 7 days before menses starts. Once menses begins and hormone withdrawal continues, many symptoms lessen. So the timing fits the late luteal phase—roughly a week before the next period. The other options don’t align with this pattern: those days would occur during or after menses, or mid-cycle, when PMS symptoms aren’t typically at their peak.
