What is a period?

In this guide, we’ll discuss menstruation and its connection to Endometriosis. 


What is a period?

A ‘period’ refers to the number of days during which menstrual bleeding occurs in the menstrual cycle. The menstrual cycle is the length of time between the first day of one period and the first day of the next. This natural process is driven by hormonal fluctuations, resulting in the shedding of blood and tissue that sheds from the lining of the womb (known as the endometrium) which is expelled out through the vagina.

Menstrual cycle details

Menstruation typically occurs approximately every month, with an average cycle length of 28 days. However, a range of 23-35 days is considered normal, when a pregnancy has not occurred, and it usually lasts anywhere between two to eight days, with an average of four to six.


Most individuals use menstrual products like sanitary pads, tampons, menstrual cups or re-usable period underwear to manage this natural process.

Variability in periods


The characteristics of menstruation, including its length, colour, flow, and timing, can vary significantly from person to person. Factors like age and contraceptive use can also influence these variations. There is a wide range in what can be considered normal, once established, your periods should be regular, consistent, and they shouldn’t interfere with your day-to-day life and activities.
