Introduction
A woman's reproductive system differs from a man's because it goes through regular cycles, which prepare the body for potential pregnancy and childbirth. This recurring process is known as the menstrual cycle and its most noticeable feature is vaginal bleeding, commonly referred to as menstruation, a woman's period, or menses.
The menstrual cycle can offer significant insights into your health. Changes in its regularity, intensity, or associated symptoms can provide valuable information about your physical and emotional condition.
Acquiring the skill of tracking your menstrual cycle and managing any irregularities that may arise can contribute positively to your overall well-being.
Unfortunately, due to societal stigma and a lack of education, menstruation has often been shrouded in myths, misinformation, and embarrassment.
Whether you're someone who experiences menstruation, a friend or family member seeking to support a loved one, or just someone curious about this natural phenomenon, this blog is your gateway to a deeper understanding of menstruation.
What is Menstruation?
Menstruation, commonly called ‘period’, is a woman’s monthly bleeding. It is a crucial part of the menstrual cycle.
When you menstruate, your body discards the monthly buildup of the uterus lining that has developed in preparation for a potential pregnancy.
Menstrual blood- partly blood and tissue from the inside of your uterus- flows from your uterus through your cervix and passes out of the body through the vagina.
The bleeding typically lasts for a few days, although the duration can vary from person to person. The average menstrual flow lasts around 4-7 days.
What is a Menstrual Cycle?
The menstrual cycle is the monthly series of physiological changes and hormonal fluctuations that prepare the body for the potential of pregnancy.
It encompasses the time between the first day of your period to the first day of your next period. While the duration of each person's cycle may vary slightly, the process remains the same.
The cycle repeats monthly from menarche (i.e., the first menstrual bleeding during puberty) to menopause (end of menstrual cycles between 45 to 55 years of age), allowing fertilization and pregnancy.
What is the Typical Length of a Menstrual Cycle?
The average menstrual cycle lasts 28 days. However, it is considered normal for a cycle to range in length from 21 to approximately 35 days.
At What Age does Menstruation begin?
On average, menstruation usually begins during puberty, which typically occurs between the ages of 10 and 15, and continues until menopause (between the ages of 45 and 55). However, the timing and regularity of menstrual cycles can vary throughout a woman's reproductive years.
Phases of Menstrual Cycle
The menstrual cycle is a complex and coordinated series of events that involves the brain, ovary, and the uterus.
The hypothalamus in the brain releases gonadotropin-releasing hormone (GnRH), which signals the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
These hormones stimulate the ovary to produce estrogen and progesterone, regulating the cycle and preparing the uterine lining for a potential pregnancy.
If pregnancy doesn't happen, the uterine lining is shed, leading to menstruation.
1. The Follicular phase
During this phase, follicle-stimulating hormone (FSH) is released by the pituitary gland, stimulating the growth of several follicles in the ovaries. Each follicle contains an egg, but usually, only one follicle becomes dominant and continues to develop.
As the dominant follicle matures, it produces increased levels of estrogen. Estrogen helps thicken the endometrium in preparation for a potential pregnancy. It also stimulates the production of luteinizing hormone (LH), which triggers ovulation.
This phase typically takes place from days 6 to 14 (Day 1-5 counted for the menstruation phase).
2. Ovulation
Ovulation marks the release of the mature egg from the ovary. This usually occurs around the middle of the menstrual cycle. LH surge triggers the release of the egg, which then travels through the fallopian tube toward the uterus.
Ovulation is the most fertile phase of the menstrual cycle, and if fertilization occurs, it can lead to pregnancy.
This phase occurs roughly at about day 14 in a 28-day menstrual cycle.
3. The Luteal phase
Following ovulation, the luteal phase begins. This phase lasts from about day 15 to day 28.
The ruptured follicle from which the egg was released transforms into a structure called the corpus luteum.
The corpus luteum produces progesterone, which further thickens the endometrium, preparing it for the implantation of a fertilized egg.
Should the egg meet sperm and become fertilized, it may implant into the thickened uterine lining, leading to pregnancy. Hormones continue to support the pregnancy.
If fertilization and implantation do not occur, the corpus luteum eventually degenerates, leading to a decrease in hormone levels.
4. Menstruation
The drop in estrogen and progesterone triggers the shedding of the lining of the uterus, causing menstruation. This phase usually lasts from the first day to the fifth day of your menstrual cycle.
After menstruation, the follicular phase begins. This cycle repeats until pregnancy happens or other factors disrupt it.
Premenstrual Syndrome (PMS)
Premenstrual Syndrome or PMS is a set of physical and emotional symptoms that many people with menstrual cycles experience in the days or weeks leading up to their period. These symptoms can vary widely, affecting individuals differently in terms of intensity and length.
Common PMS symptoms include
- Mood swings
- Irritability
- Bloating
- Breast Tenderness
- Headaches
- Fatigue
- Food cravings
- Sleep disturbances
These symptoms can be inconvenient and uncomfortable, sometimes even interfering with daily activities and relationships.
Talk to your doctor or nurse if your symptoms are causing you distress or impacting your everyday activities.
The exact cause of PMS is not entirely clear, but hormonal fluctuations, particularly in estrogen and progesterone levels, are believed to play a role.
Managing PMS often involves lifestyle adjustments like regular exercise, stress management, and dietary changes. For severe cases, medication or therapy may be recommended.
Tips to Reduce PMS Symptoms:
- Engage in regular aerobic exercise to combat issues like depression, concentration difficulties, and fatigue.
- Prioritize a healthy diet and consider avoiding caffeine, salt, and sugar in the two weeks before your period
- Ensure you get sufficient sleep, aiming for around eight hours each night. Inadequate sleep can exacerbate mood-related PMS symptoms.
- Develop healthy stress-coping strategies, like confiding in friends, journaling, or trying relaxation techniques such as yoga, massage, or meditation.
- Quit smoking, as studies have shown that smoking is associated with more severe and frequent PMS symptoms.
How to Track Your Menstrual Cycle?
Tracking your menstrual cycle can be helpful for various reasons, including understanding your fertility, planning for pregnancy or contraception, and identifying any irregularities that might require medical attention.
To keep track of your menstrual cycle, follow these steps:
- Use a physical calendar, a dedicated period-tracking app, or even a simple notebook. Many apps are available for smartphones, making it convenient to record your cycle.
- On your chosen calendar or app, mark the first day of your menstrual bleeding as "Day 1." This is the beginning of your menstrual cycle.
- Keep track of how many days your period lasts. The typical range is 3 to 7 days, but this can vary from person to person.
- Note any physical or emotional symptoms you experience during your cycle. Common symptoms include mood changes, breast tenderness, bloating, and cramps.
- If you're interested in fertility awareness, you can also monitor signs of ovulation, such as changes in cervical mucus and basal body temperature. Some apps provide features to help with this.
- When your bleeding restarts, mark it. This is the beginning of a new cycle.
- Calculate the length of your menstrual cycle by counting the days from the first day of one period to the first day of the next. The average menstrual cycle is around 28 days, but it can range from 21 to 35 days and still be considered normal.
- Pay attention to any irregularities in your cycle, such as missed periods, unusually long or short cycles, or heavy bleeding. If you notice significant changes or irregularities, consult a doctor.
- Try to record your menstrual data consistently each month. This will help you identify patterns and changes over time.
If you're experiencing menstrual problems or are trying to conceive, share your tracking information with your healthcare provider. This can assist in diagnosis and treatment.
When Should You Worry About Your Period?
You should seek medical advice or be concerned about your period in the following situations:
1. Absence of Period by Age 16: You have not had your first period by the age of 16. Delayed puberty or underlying medical conditions could be contributing factors.
2. Missed Periods: Irregular or missed periods for three months or longer. This could indicate an underlying issue, such as hormonal imbalances, polycystic ovary syndrome (PCOS), or thyroid problems.
3. Sudden Changes in Bleeding Patterns: Your periods suddenly become significantly longer, shorter, heavier, or lighter than usual. These changes could signal various health conditions, including fibroids, endometriosis, or uterine polyps.
4. Severe Pain: You consistently experience severe pain during your period, known as dysmenorrhea.
5. Bleeding Between Periods: You notice bleeding between your regular menstrual cycles.
6. Unusual Symptoms: You have unusual symptoms like heavy bleeding with clots, severe mood swings, extreme fatigue, or other concerning issues that significantly disrupt your daily life.
7. Persistent Symptoms You have tried managing PMS symptoms or period-related discomfort through lifestyle changes and home remedies, and the symptoms persist or worsen.
8. Potential Pregnancy: You have had sex and your period is at least five days late. Consider taking a pregnancy test, especially if you've had unprotected sex.
9. Birth Control Interruption: You have been on hormonal birth control (such as birth control pills, patches, or injections) and your period hasn't returned within three months after discontinuing it.
Note: Every person's menstrual cycle is unique, and some degree of variability is normal. However, if significant and persistent changes are affecting your daily life, you should consult with a doctor. This will rule out any underlying health issues and help you get appropriate guidance or treatment.
Tips for Managing Menstruation
- Choose menstrual products that you are comfortable with, whether it's pads, tampons, menstrual cups, or period underwear.
- Change your menstrual products regularly to prevent the risk of infection. Pads and tampons should typically be changed every 4-8 hours, depending on your flow.
- Dispose of used menstrual products in a hygienic and environmentally friendly manner.
