Getting a Handle on your PMS

Your menstrual cycle is composed of two distinct phases over an average of 28 days. Your cycle begins with the first day of your period - day 1. From this point until roughly day 1 until day 14 is what’s known as the follicular phase. Days 15 to 28 is known as the luteal phase. Ovulation occurs right in the middle around day 14. PMS or premenstrual syndrome typically occurs 5-7 days before your period starts. While many women will experience some sort of PMS each month, the degree will vary greatly from woman to woman.
