Menstruation is a natural process that women experience monthly. Knowing the first day of your period and how to know if your menstrual cycle is normal is important to maintaining good reproductive health.

In this article, we will discuss everything you need to know about your menstrual cycle.

What is the menstrual cycle and how does it work?

The menstrual cycle is the physiological process that occurs in a woman's body, and that allows the body to prepare for a possible pregnancy. This process begins with the first day of menstruation and ends with the beginning of the next.

The menstrual cycle is controlled by a series of hormones produced by the brain and ovaries.

The process begins when the brain sends a signal to the ovaries to start producing hormones, including estrogen and progesterone. These hormones cause the lining of the uterus to thicken and prepare for a possible pregnancy.

In the middle of the menstrual cycle, the ovary releases an egg, in a process called ovulation. If the egg is not fertilized by a sperm, it disintegrates and is eliminated from the body during menstruation. If the egg is fertilized, it can implant in the lining of the uterus and begin a pregnancy.

If there is no pregnancy, the body produces fewer hormones and the lining of the uterus is shed, starting menstruation.

This process lasts approximately 21 to 35 days, depending on each woman, and can vary in terms of duration and amount of menstrual flow. Check out these apps to keep a closer eye on your cycle .

It is important to mention that the menstrual cycle can be affected by factors such as age, health, the use of certain medications, among others.

There are also menstrual cycle disorders, such as amenorrhea (absence of menstruation), dysmenorrhea (menstrual pain), and premenstrual syndrome (PMS), which may require medical attention. It can also be accompanied by constipation and here you can find out the reasons .

How is the first day of the period determined?

To determine the first day of the period, it must be taken into account that menstrual bleeding can vary in amount, duration and flow.

The first day of menstruation is generally considered to be the day when bleeding is heavy enough to require the use of a pad or tampon.

It is important to keep a record of the menstrual cycle, noting the first day of menstruation and the length of the cycle.

This can help predict when your next period will occur and identify any changes in your cycle that may require medical attention.

In some cases, the first day of the period may not be clear or small leaks may occur before the main menstrual bleeding.

In these cases, it is advisable to consult with a health professional to determine the first day of the period and obtain more information about menstrual health.

How do I know if my menstrual cycle is normal?

The menstrual cycle runs from the first day of your menstruation (also known as your period or period) to the first day of your next period.

The average length of the menstrual cycle is in the range of 25 to 30 days, although it can vary from as little as 21 days to more than 35 days. Cycle length may vary from person to person as each body is unique.

Additionally, your cycle length may fluctuate from month to month. During the menstrual period, it is common to experience bleeding that can last between 2 and 7 days.

The amount of bleeding can also vary, but specialists point out that it is normal if no more than four sanitary pads or tampons are needed a day .

In addition to the duration and amount of menstrual bleeding, other symptoms related to the menstrual cycle can also indicate whether your menstrual cycle is normal.

For example, Premenstrual Syndrome (PMS) is a set of symptoms that can occur in the days before menstruation, such as mood changes , headaches, bloating, and breast tenderness. But we will explain this to you later.

However, some changes in the cycle can be a sign that something is not working correctly in the body.

If your menstrual cycle changes suddenly, for example, if your menstrual bleeding becomes heavier or lasts longer than normal, or if you have severe pain or other unusual symptoms, it is important to consult with a health care professional to determine if there are any any problem.

Although there are certain general parameters to determine if your menstrual cycle is normal, it is best to pay attention to the characteristics of your own cycle and seek medical attention if you notice any significant changes.

Do you know what Premenstrual Syndrome is?

Premenstrual syndrome (PMS) is a set of physical, emotional and behavioral symptoms that some people experience before their menstrual period begins. These symptoms tend to appear during the luteal phase of the menstrual cycle, which is the period of time from ovulation to the start of menstruation.

PMS symptoms can vary widely between people and in intensity. Some of the most common symptoms include:

  • Mood changes, such as irritability, sadness, anxiety, or sudden changes in mood.
  • Feeling of bloating and fluid retention.
  • Fatigue or excessive tiredness.
  • Difficult to focus.
  • Changes in sleep patterns.
  • Headaches or migraines.
  • Breast tenderness.
  • Food cravings, especially sweet or salty foods.
  • Changes in intestinal habits.
  • Increased acne.

These symptoms usually begin days or even a week before the start of the menstrual period and tend to disappear once menstruation has started. However, it is important to note that not all people experience PMS in the same way or to the same extent.

What causes it?

It is believed to be related to hormonal fluctuations that occur during the menstrual cycle. As levels of hormones such as estrogen and progesterone rise and fall throughout the cycle, they can trigger a series of changes in the body that result in the characteristic symptoms of PMS.

How much blood can I lose during my menstruation?

In general, it is estimated that between 1 and 6 tablespoons of blood are lost during each menstrual period.

The consistency of the discharge can be light or have a certain thickness, and its color can vary from a dark red tone to brown or pink.

When experiencing your first menstrual period, it is normal for the first few times to be short-lived or very light.

If the amount of bleeding is so profuse that you need to change sanitary pads or large tampons every hour, we recommend that you visit your trusted doctor.

It should be noted that menstrual periods are individualized and may differ from one person to another.

What is considered "normal" for one person may not be "normal" for another, and these patterns can also change over time.

It is important to note that some contraceptive methods or health conditions can influence the nature of your menstrual period.

Keep conscious observation of your patterns and, if you have any doubts or concerns, do not hesitate to consult a health professional.

Frequent questions

What happens if I don't have a period in a month?

The absence of menstruation for a month can be an early indication of pregnancy, although it is not necessarily the only cause. There are times when a missed period is not directly related to pregnancy and can occur for no apparent reason. This scenario is particularly common during the first few years after your first menstruation. In addition to pregnancy, there are multiple factors that can influence the regularity of the menstrual cycle and the presence or absence of a period.

What does it mean if my menstruation is irregular?

It is a common experience to experience irregular menstrual cycles and periods at some point in life, especially in the first few years after menarche. Some people's menstrual cycles may have notable irregularities and are often accompanied by constipation . This may be due to both the unique nature of the body's functioning and potential health problems. One of the causes of menstrual irregularity may include hormonal factors, stress, changes in body weight, medical disorders and other elements.
