What Is Menstrual Cycle?

The menstrual cycle is a monthly process in reproductive-age women, preparing the body for pregnancy. It begins on the first day of menstruation and ends just before the next one, typically lasting normal menstrual cycle duration of 21–35 days. Variations can occur due to changes in health, stress, or lifestyle.

The Four Phases of Menstrual Cycle

1. Menstrual Phase (Days 1–5): Shedding of the uterine lining, marked by bleeding.

2. Follicular Phase (Days 1–13): Follicle growth and rising estrogen levels.

3. Ovulation (Day 14): Mature egg released. Luteinizing hormone peaks.

4. Luteal Phase (Days 15–28): Progesterone rises. Uterine lining readies for possible pregnancy. If there is no fertilisation, estrogen and progesterone levels drop, triggering menstruation.

How to Count & Calculate Your Cycle

How to calculate menstrual cycle:

• Use a menstrual cycle calculator or manually count days from Day 1 of one period to Day 1 of the next.
• Keep track for at least 3–6 months to determine your cycle pattern.
• How to count menstrual cycle: Count bleeding days as Day 1.

Normal & 21-Day Menstrual Cycle Causes

A normal menstrual cycle duration ranges from 21 to 35 days. A consistent 21-day menstrual cycle may signal shorter follicular or luteal phases. The triangle of causes includes stress, elevated metabolism, or minor hormonal imbalances, which are often manageable.

Hormonal Regulation of Menstrual Cycle

Hormones provide flow and fluidity in your cycle:

• Estrogen promotes uterine lining growth.
• Progesterone stabilises the lining post-ovulation.
• FSH triggers follicle maturity.
• LH surges to release the egg.

Disturbances in this system can cause cycle irregularities and discomfort.

Common Menstrual Cycle Problems

• Irregular menstrual cycle: Varying cycle lengths or skipped periods, often due to stress, diet, or health issues.

• Painful periods (dysmenorrhea): Often linked to uterine contractions and prostaglandins.

• Heavy bleeding (menorrhagia): Could signal fibroids, vitamin deficiencies, or contraceptive changes.

• Skipping periods (amenorrhea): May indicate excessive dieting, stress, or underlying medical conditions.
  

Reasons for Delay in Menstrual Cycle

Reasons for delay in menstrual cycle may include:

• High stress or emotional upheaval
• Low body weight or fitness extremes
• Hormonal disorders like PCOS or thyroid imbalance
• Medications, travel, or illness interruptions

Long delays or multiple irregular cycles should be discussed with a healthcare provider.

Tips to Support a Healthy Cycle

• Track cycle regularly using apps or a menstrual cycle calculator.
• Maintain a balanced diet, rich in whole grains, lean proteins, and healthy fats.
• Manage stress through yoga, meditation, or counselling.
• Exercise moderately, balancing cardio, strength, and flexibility.
• Get quality sleep — critical for hormonal balance.
• Avoid smoking and limit alcohol, both of which affect hormone regulation.
• Seek medical support if you struggle with persistent menstrual cycle problems.
