Menstruation or period is the monthly shedding of the uterine lining, in response to the hormones produced by the women’s body. Its function is to prepare the female body for potential pregnancy and also to discharge unneeded tissue and materials from the uterus.


The average period cycle of a woman is 28 days long, however, it can range from 25 to 30 days.¹ The typical volume of blood lost during menstruation is approximately 30 ml.¹ Thus, vaginal bleeding that soaks through one or more pads or tampons every hour for several hours in a row during one’s period is considered abnormal.
