Your Monthly Cycle

Following your first period, your body settles into a cycle of ovulation and menstruation, lasting around 28 days. It is a natural part of being a woman. But how does it all work?

Your monthly cycle is a natural part of being a woman. To understand how it works, have a look at the women’s anatomy.


The external reproductive organs include the outer and inner labia and the clitoris. The outer labia are also called the labia majora. The labia minora (inner labia) cover the vaginal and urethral openings. They meet in front of the clitoris, which is covered by a thin mucous membrane, a mucosa. The clitoris, because of its sensitivity, plays a big role in sexual arousal. Inside, the vagina is connected to the cervix, which is the lower part of the uterus. Further inside, the uterus is wider and this is where an egg is deposited each cycle and where the embryo and fetus will develop during gestation.



This cycle lasts around 28 days; it is not uncommon, however, for cycles to be as short as 21 days or as long as 35 days. The interaction of female sex hormones causes a mature egg to leave one of the two ovaries and travel down the Fallopian tube towards the uterus. This takes around three to four days. In the meantime, the uterine lining has been prepared to receive a fertilised egg, becoming thicker and enriched with nutrients. If the egg is not fertilised during this time by a sperm cell, the upper layers of the endometrium disintegrate and are sloughed off. This causes bleeding of your period.

This bleeding – what we call “flow” – is not always the same. Life events – having a baby, dieting, stress, different contraception methods – can all affect how heavy the flow is. Flow changes from woman to woman, and from month to month. That’s why tampons are available in many formats and absorbencies. With the right products on your side, you can feel protected and comfortable every day of the month - so that nothing will stop you from enjoying life to its fullest.
