Premenstrual syndrome (PMS) is the name given to a collection of physical and emotional symptoms that can occur in the two weeks before you have your period. These symptoms usually get better once your period starts and often disappear by the end of your period.
Nearly all women have some premenstrual syndromes. Each woman’s syndromes are different, and may vary from month to month. Between one and two in 20 women (5–10%) get PMS which is severe enough to prevent them from getting on with their daily lives. A very small number of women get a more intense form of PMS called premenstrual dysphoric disorder.
