The start of your period indicates the start of your menstrual cycle. Each month a woman’s body prepares itself for pregnancy with the lining of the uterus wall (endometrium) thickening in readiness to receive a fertilised egg. If the egg is not fertilised, the uterine wall is shed. During a woman’s period, menstrual fluid made up of blood, tissue and fluid which made up the endometrium, passes from the uterus through the opening of the cervix, through the vagina and out of the body.
