Before we understand irregular periods, it's essential to know what "regular" means. A regular menstrual cycle is a predictable pattern that your body follows.
Key characteristics of a regular period include
Cycle Length
Typically between 21 and 35 days. The average is around 28 days.
Consistency
Your cycle length is fairly consistent from month to month. It might vary by a day or two, but not by a week or more.
Duration
The period itself (bleeding) lasts between 2 and 7 days.
Flow
The flow is predictable in its pattern; it might start light, get heavier for a few days, and then taper off. There are no extremely heavy clots or sudden, massive flooding.
Think of your cycle as a monthly report from your body; a regular one is a consistent, predictable document.
When Do We Say irregular periods?
You are considered to have irregular periods if they consistently fall outside the norms of a regular cycle. This can manifest in several ways:
Cycle Timing
- Cycles shorter than 21 days.
- Cycles longer than 35 days.
- The length of your cycle varies significantly from month to month (e.g. 28 days one month, 45 days the next).
Flow and Duration
- Bleeding for more than 7 days (menorrhagia).
- Bleeding lasting less than 48 hours.
- Extremely heavy bleeding where you soak through a pad or tampon every 1-2 hours.
- Very light spotting instead of a proper flow.
Missing Periods
Not having a period for 90 days or more (and you are not pregnant, postpartum, or menopausal).
Other Symptoms
- Severe pain (dysmenorrhea) that disrupts your life.
- Bleeding or spotting between periods.
- Bleeding after menopause.
Common Causes of Irregular Periods
Many causes of Irregular periods are very common, and the causes range from lifestyle factors to underlying medical conditions.
Hormonal Imbalances
The most common cause of irregular periods. Your menstrual cycle is regulated by hormones such as estrogen and progesterone.
Polycystic Ovary Syndrome (PCOS)
A common condition where high levels of androgens (male hormones) prevent ovulation.
Thyroid Issues
Both an overactive (hyperthyroidism) and an underactive (hypothyroidism) thyroid can cause irregular periods.
Perimenopause
The transition to menopause is when hormones fluctuate widely.
Lifestyle Factors
Significant Stress
High stress increases cortisol, which can interfere with the hormones that regulate your cycle.
Sudden and extreme weight change
Body fat produces estrogen; too much or too little can stop ovulation.
Strenuous Exercise
Intense physical training can lower body fat and stress the body, halting periods.
Poor Diet
Lack of essential nutrients can affect hormonal production.
Medications
- Certain types of birth control (especially when starting or stopping).
- Antidepressants, antipsychotics, and thyroid medications.
Medical Conditions
Uterine Fibroids or Polyps
Non-cancerous masses in the uterus can cause heavy or prolonged bleeding.
Endometriosis
A condition where uterine-like tissue grows outside the uterus, causing pain and irregular periods.
Pelvic Inflammatory Disease (PID)
An infection of the reproductive organs.
How to Track Your Period
Goal
To understand your unique cycle pattern, predict your period, and identify any irregular periods.
What to Track
Start Date
The first day of bleeding is the first day of your cycle.
End Date
The last day you bleed.
Flow
Note if each day is Light, Medium, Heavy, or Spotting.
Symptoms
Record physical (cramps, bloating, acne) and emotional (mood swings, fatigue) changes.
How to Track
Best Method
Use a Period Tracking App. Input your data, and the app predicts your next period and fertile window.
Simple Method
Mark a Calendar with the start date and symptoms each month.
Detailed Method
Keep a Journal for more in-depth notes.
Key Calculation
Cycle Length: Count the days from Day 1 of one period to the day before your next Day 1. A typical cycle is 21-35 days.
Why It's Useful
· Predicts your next period.
· Identify your personal symptom patterns.
· Provides valuable data for your doctor if concerns
When to See a Doctor
While the occasional irregular periods cases are normal, certain signs warrant a visit to your healthcare provider (a gynaecologist or your primary care doctor).
You should make an appointment if you experience
- Your periods stop suddenly for more than 90 days (and you're not pregnant).
- Your periods become consistently irregular after being regular.
- You bleed much more heavily than usual, soaking through one or more pads or tampons every hour for several hours.
- You bleed for more than 7 days.
- You experience bleeding between periods.
- You have severe agonising pain before, during, or after your period.
- You develop a fever or feel sick after using tampons.
- Do you have any bleeding after menopause?
Seek emergency care if you experience
Very heavy bleeding accompanied by dizziness, fainting, or signs of severe anemia (extreme paleness, shortness of breath).
How to Lower Your Risk of Irregular Periods
To promote a regular menstrual cycle, focus on supporting your body's natural hormonal balance through key lifestyle habits.
Maintain a Healthy Weight
Being significantly underweight or overweight disrupts estrogen, which can stop ovulation.
Eat a Balanced Diet
- Focus on: fruits, vegetables, whole grains, and lean proteins.
- Include healthy fats (avocado, nuts) for hormone production.
Manage Stress
- Chronic stress raises cortisol, which interferes with period-regulating hormones.
- Practice yoga, meditation, or ensure you get 7-9 hours of sleep.
Exercise Moderately
Find a balance. Both a sedentary lifestyle and excessive, intense exercise can cause irregular periods.
Limit Alcohol & Avoid Smoking
Both can disrupt hormone levels and lead to irregular periods.
Conclusion
Irregular periods are a common issue, and understanding the difference between a normal variation and a potential red flag is key to managing your reproductive health.
Tracking your cycle and paying attention to changes empowers you to have an informed conversation with your doctor and get the care you need.
