Why Do Periods Get Late? Possible Causes and Solutions

You’ve circled the date on the calendar, planned your comfort snacks, and made arrangements, and yet your period is MIA. Before you lose your mind and start heading down the road of worst-case scenarios, take a deep breath. A late or delayed period is more common than you may realise, and not necessarily a negative thing. Although an average menstrual cycle can take up to 21 to 35 days, no one expects an absolute, regimented schedule. You can miss your cycle because of several reasons. The reason could be as common as being stressed out or changes in one's lifestyle or something more serious like an underlying health issue.

This blog explains the most common reasons for late periods, what to look out for in terms of symptoms, and how to know if a delay is likely to be more than an isolated incident. We’ll also cover late-period remedies, prevention tips, and when it's time to check in with a healthcare professional.

Ready to decode what’s going on with your cycle? Let’s get into it.

The menstrual cycle: A monthly symphony

Think of your menstrual cycle as a monthly hormonal shift that’s directed by your brain, impacting your ovaries and uterus. It usually spans around 28 days, though anything between 21 to 35 days is still considered normal.

Here’s the backstage breakdown:

  • Phase 1 – menstrual phase: This is when your period actually happens. The uterus sheds its lining, and this flow typically lasts 3-7 days. It’s your body’s way of saying, “No pregnancy this time, let’s reset.”

  • Phase 2 – follicular phase: It begins with your period and lasts until ovulation. During this phase, the brain instructs your ovaries to prepare some follicles (small sacs that hold immature eggs) to be ready. Oestrogen increases, preparing the uterine lining for possible pregnancy.

  • Phase 3 – ovulation: Approximately at the midpoint of the cycle, a single mature egg is released from the ovary. It's the main attraction and only remains for 12-24 hours, hoping for possible fertilisation.

  • Phase 4 – luteal phase: After ovulation, progesterone increases as the body readies for a potential pregnancy. If you are not pregnant, your hormones will plummet, and you will begin your next period. 

When this hormonal balance is disrupted because of stress, health issues, or adjustments in your lifestyle, it can disrupt the rhythm, causing delayed periods or missed periods. Knowing how your cycle is supposed to ideally work, you will be well equipped to know when something is off.​

Decoding late menstruation: What's going on down below?

A late menstrual period is menstruation that occurs after an anticipated date, and it is usually over five days late. Late menstruation can be caused by many factors, such as stress, changes in lifestyle, and underlying health issues. It is important to identify the patterns and deviations in your cycle early for early intervention.​

Spotting the signs: Late period symptoms

When periods are late, you might experience:​

  • Abdominal cramps without bleeding

  • Mood swings

  • Breast tenderness

  • Fatigue

  • Nausea

  • Bloating​

These late-period symptoms can sometimes mimic early pregnancy signs or indicate hormonal imbalances.​

Unravelling the mystery: Reasons for not getting periods

Several factors other than pregnancy can lead to a delayed period cycle:

  1. Stress: Ongoing stress damages the hypothalamic axis, breaking up hormone secretion and resulting in late periods.

  2. Weight changes: Major weight increase or reduction may disrupt hormonal levels, resulting in late menstruation.

  3. Polycystic ovary syndrome (PCOS): A prevalent syndrome where hormonal disparities cause irregular or missed periods.

  4. Thyroid diseases: Hyperthyroidism and hypothyroidism are known to influence menstrual regularity.

  5. Perimenopause: Menstrual change is caused during the transitional stage prior to menopause.

  6. Too much exercise: Too much exercise can delay ovulation, causing late periods.

  7. Chronic illnesses: Certain illnesses such as diabetes or coeliac disease can impact menstruation.​

Quick Explainer

Stress, weight changes, PCOS, thyroid diseases, perimenopause, and excessive exercise are some of the common reasons for delayed periods. 

 

When to worry: Late periods and health concerns

Periods are late by 10 days: Normal or not?

A delay of up to 10 days can be within the realm of normal, especially if it's an isolated incident. However, if periods are late by 10 days consistently, it's advisable to consult a healthcare provider to rule out underlying issues.​

Late period symptoms signalling health issues

Persistent late-period symptoms, such as severe cramps, excessive bleeding once menstruation resumes, or prolonged absence of periods, may indicate health concerns like PCOS, thyroid disorders, or other hormonal imbalances. Early diagnosis and treatment are crucial.

Natural approaches: Home remedies for late periods

Though consulting a medical practitioner is necessary for recurring problems, certain home remedies for delayed periods are:

  • Healthy weight: Gaining and maintaining a healthy weight helps control hormonal balance.​

  • Balanced nutrition: Eating a diet containing fruits, vegetables, and whole-grain foods aids overall health.​

  • Regular exercise: Regular exercise in moderation helps control menstrual cycles.​

  • Stress reduction: Techniques such as yoga, meditation, and controlled breathing help lower stress levels.

  • Herbal remedies: to be considered after consultation with your doctor

Keep in mind that although these cures for late periods during the latter part of the period can be helpful, they do not substitute expert medical consultation.​ It is advised to visit your doctor if you notice irregular periods for several months, or notice a sudden change in your bleeding flow. 

Quick Tip

Stabilise menstrual cycles by maintaining a healthy weight, managing stress, exercising, and eating a healthy diet.

Embracing your cycle with confidence

Late periods can result from numerous different factors, ranging from lifestyle issues to underlying diseases. Knowing what causes not to get periods and identifying late period symptoms are imperative steps toward taking care of your reproductive health. If you observe regularly delayed menstruation, early medical consultation means timely diagnosis and proper treatment.
