Thirty healthy young women volunteered to complete questionnaires concerning physical and psychological symptoms during a full menstrual cycle. A maximal incidence of minor physical and psychological symptoms was observed in the first few days of menstruation. This was preceded by a gradual rise in the level of symptomatology during the premenstruum.
