Premenstrual syndrome and menopause Booklet

Premenstrual syndrome (also known as PMS) is when women who have periods experience distressing symptoms in the days or even weeks leading up to starting their period. PMS encompasses a vast array of psychological symptoms such as depression, anxiety, irritability, loss of confidence and mood swings. There are also physical symptoms, such as bloatedness and breast tenderness.

PMS is identified when symptoms occur – and have a negative impact – during the luteal phase of your menstrual cycle. The luteal phase occurs between ovulation (normally midcycle, around day 14) and starting your period (usually around day 28). Although the average length of the menstrual cycle is 28 days, it can vary greatly between women and you may find the length of your cycle varies from month to month.
