Irregular Periods

The menstrual cycle is a natural part of a woman’s life. For most women, periods come every month and follow a pattern. The average cycle is about 28 days, and bleeding usually lasts 4 to 7 days. However, not every woman has the same cycle. Some differences are normal. Irregular periods happen when your cycle does not follow a regular pattern. This may mean your period comes too early, too late, is very heavy, very light, or you skip periods completely. Understanding irregular periods helps you know when changes are normal and when you should see a doctor.

What Are Irregular Periods?

Your menstrual cycle begins on the first day of your period and ends the day before your next period starts. Although 28 days is the average length, a normal cycle can range between 21 and 35 days in adults. A period is considered irregular if the gap between cycles keeps changing significantly from month to month. Missing three or more periods in a row, bleeding for longer than seven days, experiencing very heavy bleeding, or spotting between periods are also signs of irregularity.

Irregular cycles are especially common during puberty, when a girl first starts menstruating. During this time, hormones are still balancing, so it may take a few years for periods to become regular. Irregular periods are also common during perimenopause, which usually begins in the late 40s or early 50s, as hormone levels start to change again.

Why Tracking Your Period Is Important?

Tracking your cycle helps you understand what is normal for your body.

You can track your period by:

• Using a period tracking app
• Writing dates in a diary
• Marking your calendar

It is helpful to note:

• The first day of bleeding
• How many days your period lasts
• Whether the flow is light, normal, or heavy
• If you have cramps, mood swings, headaches, or fatigue
• Any spotting between periods

This information is very useful if you need to speak to a doctor.

What Causes Irregular Periods?

There are many reasons why periods become irregular. Some are normal. Others may need medical attention.

Common Causes

1. Puberty
   When periods first start, it takes time for hormones to balance. Cycles may be irregular for a few years.
2. Menopause
   Before menopause, periods often become irregular.
3. Pregnancy
   A missed period can be an early sign of pregnancy.
4. Birth Control
   Hormonal contraception such as:
   • Birth control pills
   • Contraceptive injections
   • Intrauterine system (IUS)
     can change your cycle.
5. Weight Changes
   Losing or gaining a lot of weight quickly can affect hormones.
6. Stress and Anxiety
   Emotional stress can disturb your cycle.
7. Too Much Exercise
   Very intense workouts can stop or delay periods.

Medical Conditions That Can Cause Irregular Periods

Some health conditions can also cause irregular bleeding:

• Polycystic Ovary Syndrome (PCOS) – causes hormone imbalance
• Underactive thyroid (Hypothyroidism) – slows down hormone production
• Uterine fibroids
• Endometriosis
• Pelvic infections

Other symptoms may include:

Extreme tiredness

Weight gain

Extra facial or body hair

Acne

Severe pelvic pain

How Are Irregular Periods Diagnosed?

If you visit a doctor, they will:

1. Ask about your menstrual cycle
2. Ask about your medical history
3. Perform a physical exam
4. Possibly do a pelvic exam

They may also recommend tests.

Common Tests

1. Pelvic Ultrasound

Uses sound waves to check for:

• Fibroids
• Polyps
• Ovarian cysts

2. Endometrial Biopsy

A small tissue sample is taken from the uterus lining to check for:

• Hormone problems
• Endometriosis
• Abnormal cells

3. Hysteroscopy

A small camera is inserted into the uterus to look for abnormal bleeding causes.

These tests help find the exact reason for irregular periods.

Treatment for Irregular Periods

Treatment depends on the cause.

Sometimes simple lifestyle changes are enough. In other cases, medication or surgery may be needed.

Medications

1. Hormonal Birth Control

Birth control pills, rings, injections, or IUDs can:

• Regulate periods
• Reduce heavy bleeding
• Make cycles predictable

They are often used for:

• PCOS
• Fibroids
• Endometriosis

2. Tranexamic Acid

This medicine helps reduce heavy bleeding.
You take it at the start of your period.

3. Pain Relievers

Medicines like ibuprofen can help with cramps and pain.

4. Hormone Therapy

Used during perimenopause.
Helps regulate periods and reduce symptoms like:

• Hot flashes
• Vaginal dryness

Always discuss risks with your doctor.

5. Antibiotics

Used if an infection is causing irregular bleeding.

6. Gonadotropin-Releasing Hormone (GnRH) Agonists

These medicines shrink fibroids and reduce heavy bleeding.
They temporarily stop periods.

Surgical Treatments

If medicines don’t work, surgery may be recommended.

1. Endometrial Ablation

Destroys the uterus lining to reduce bleeding.
Not recommended if you want future pregnancy.

2. Myomectomy

Removes uterine fibroids.

3. Uterine Artery Embolization

Blocks blood supply to fibroids.

4. Hysterectomy

Removes the uterus completely.
This is usually a last option for severe cases.

Can Irregular Periods Be Prevented?

Not all irregular periods can be prevented, especially those caused by natural hormonal changes. However, maintaining a healthy lifestyle can reduce the risk. Eating nutritious foods, exercising moderately, sleeping well, and managing stress are simple but powerful ways to support regular cycles. Avoiding extreme diets and intense overtraining is also important. Regular medical check-ups help detect issues early before they become serious.

Is It Normal to Miss One or Two Periods?

Missing one or two periods occasionally is not always a cause for alarm. Life changes such as stress, travel, illness, or changes in routine can temporarily affect your cycle. However, if you miss three consecutive periods or experience unusual symptoms, it is important to consult your healthcare provider. Small variations in timing are common. Every woman’s “normal” is different. What matters most is recognizing changes that are unusual for you.

Final Thoughts

Irregular periods are common and often not serious. They can happen because of hormonal changes, stress, weight changes, birth control, or medical conditions. Most causes are manageable and treatable with proper care. The key is to listen to your body and track your cycle regularly. If something feels unusual or concerning, do not ignore it. Early consultation with a healthcare provider can prevent complications and give you peace of mind. Your menstrual cycle is an important sign of your overall health. Taking care of it means taking care of yourself.
