Understanding the duration of the menstrual cycle: Everything you need to know

Comprendre la durée du cycle menstruel : Tout ce qu'il faut savoir

The menstrual cycle is a subject as fascinating as it is important for many women. Indeed, it encompasses a series of physiological and hormonal changes that, although often misunderstood, are perfectly natural. Knowing the duration of one’s cycle, as well as the phases it comprises, can help to better understand one’s body and needs. This article will provide you with all the necessary details to better comprehend the dynamics of the menstrual cycle, including its average length, possible variations, and their causes.

What is the menstrual cycle?

The menstrual cycle encompasses a series of processes within the female organism, aimed at preparing the body for a potential pregnancy. It begins on the first day of menstruation and ends with the onset of the next menstruation. Composed of four main phases, this cycle can vary from one woman to another.

– The menstrual phase: menstruation

The first day of menstruation marks the official start of the cycle. In the absence of pregnancy, the endometrium, the lining that covers the uterus, breaks down and is expelled as blood loss. On average, this phase lasts between 3 and 7 days, but once again, this can vary depending on each woman.

– The follicular or estrogenic phase

After menstruation, the body prepares for ovulation. The level of estrogen hormone starts to rise, promoting the regeneration and thickening of the endometrium. The release of follicle-stimulating hormone also stimulates the ovarian follicles, which contain the eggs. This is the ideal time to prepare for a potential fertilization!

– The ovulation phase

This phase is characterized by a peak in luteinizing hormone, leading to the release of an egg from the follicle. The egg then begins its journey to the uterus, while the endometrium continues to thicken, thus preparing to potentially receive the fertilized egg.

– The luteal phase

During this phase, the empty follicle transforms into the corpus luteum, which secretes progesterone. This hormone’s role is to maintain a rich endometrium ready for a potential pregnancy. If fertilization does not occur, the endometrium breaks down, marking the return to the menstrual phase.

What is the average duration of a menstrual cycle?

In France, an average menstrual cycle lasts 28 days. This is an average, with each woman having her own specifics, ranging from shorter to longer cycles, which is perfectly normal.

How to calculate the duration of your menstrual cycle?

How to calculate the duration of your menstrual cycle?

To track your cycle, simply note the start date of your menstruation on a calendar. Count from this first day until the day before the next menstruation. The duration obtained will indicate the length of your cycle.

Short menstrual cycle or polymenorrhea

Duration of a short cycle

A cycle is considered short when its duration is less than 25 days. Although often without consequence, a very short cycle may be referred to as polymenorrhea, requiring particular attention.

Causes

It may result from gynecological monitoring, as this can signal conditions such as endometriosis or certain infections. A shorter cycle could also be related to anovulation, which is the absence of ovulation.

Long menstrual cycle or oligomenorrhea

Duration of a long cycle

Conversely, a cycle described as long is one that exceeds 35 days, sometimes up to 60 days. This is known as oligomenorrhea.

Why do I have a long cycle?

A long cycle generally means a prolonged follicular phase, which does not negatively impact health, just the number of ovulations per year and thus the chances of becoming pregnant.

Causes of the long cycle and monitoring

In the case of oligomenorrhea, consulting a gynecologist allows checking for the absence of diseases such as thyroid disorders or polycystic ovary syndrome, which can affect the cycle.

This journey of understanding the duration of the menstrual cycle reveals a fascinating and often unknown complexity. Every woman has a unique body, with its own rhythms and needs. Familiarizing oneself with this process can transform the perception of menstrual health. By listening to our bodies and educating ourselves, we can better manage our physical and emotional well-being. It is helpful to remember that each cycle is a new opportunity to reconnect with oneself. For my part, I have often had regular cycles until a hormonal change caused me to experience irregular cycles. This pushed me to deepen my knowledge on the subject, to understand the signs of my body, and to seek balance, both physiological and emotional. Knowledge becomes a true ally when navigating through one’s own cycles.
