Why has my period not come on time?

There are several reasons why your period might not come on time, and it's important to consider various factors that can influence your menstrual cycle. Here are some common causes of a delayed period:


1. Stress

How it affects: High stress levels can disrupt the balance of hormones that regulate your menstrual cycle, especially cortisol (the stress hormone), which can interfere with the release of reproductive hormones. This can cause your period to be delayed or skipped altogether.

What to do: Try stress-reduction techniques such as relaxation exercises, yoga, meditation, or breathing exercises.


2. Pregnancy

How it affects: One of the most common reasons for a missed period is pregnancy. If you’ve been sexually active and your period is late, it's important to rule out pregnancy.

What to do: Take a home pregnancy test to confirm whether or not you’re pregnant. If the test is positive, schedule an appointment with your doctor or healthcare provider.


3. Changes in Weight

How it affects: Significant changes in body weight, either weight gain or weight loss, can affect hormone levels, leading to irregular periods or missed periods. This is especially common in people with eating disorders or those who undergo extreme weight fluctuations.

What to do: Ensure you're maintaining a healthy, balanced diet and engage in moderate physical activity. If you're concerned about weight loss or gain, consult a healthcare professional.


4. Polycystic Ovary Syndrome (PCOS)

How it affects: PCOS is a hormonal condition that can cause irregular periods or missed periods. It often leads to imbalanced levels of estrogen, progesterone, and testosterone, which can disrupt ovulation and menstruation.

What to do: If you suspect you have PCOS, it’s important to consult with a healthcare provider for a diagnosis and treatment options.


5. Excessive Exercise

How it affects: Intense physical activity, especially if you're not eating enough to support it, can cause a disruption in hormone levels, which can lead to delayed periods or missed periods. This is often seen in athletes or those who engage in extreme exercise routines.

What to do: Aim for a balanced exercise regimen and ensure you’re consuming enough calories and nutrients to fuel your body. If the issue persists, consider seeing a doctor.


6. Thyroid Issues

How it affects: The thyroid gland controls metabolism and can influence menstrual cycles. Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can lead to irregular periods or missed periods.

What to do: If you suspect thyroid issues, a blood test can determine if your thyroid is functioning properly. Treatment typically involves medication to regulate thyroid hormone levels.


7. Changes in Birth Control

How it affects: If you've recently started or stopped taking birth control (e.g., the pill, IUD, or implant), it can affect your menstrual cycle. Hormonal birth control methods can cause periods to become lighter, heavier, or irregular, especially when you first start using them.

What to do: If you’ve recently changed birth control methods or stopped using them, give your body time to adjust. If the irregularity persists, talk to your healthcare provider.


8. Perimenopause

How it affects: As women approach menopause, which typically occurs between ages 45-55, the body goes through a transitional phase called perimenopause. During this time, menstrual cycles can become irregular or unpredictable due to fluctuations in hormones.

What to do: If you’re nearing the age of menopause and are experiencing irregular periods, it's normal, but if you have concerns, consult your doctor.


9. Chronic Illness or Medications

How it affects: Certain chronic illnesses like diabetes, endometriosis, or inflammatory bowel disease (IBD), as well as medications (especially those that affect hormones), can disrupt your menstrual cycle.

What to do: If you have a chronic illness or are taking medication, check with your doctor to see if these factors could be affecting your period.


10. Travel or Time Zone Changes

How it affects: Traveling, especially across time zones or to a different climate, can disrupt your body's natural rhythm, which may delay your period. Your body may take some time to adjust to new environments or changes in your schedule.

What to do: Give your body time to adjust. In most cases, your period will return to normal once you’ve settled into your new routine.


11. Hormonal Imbalances

How it affects: Hormonal imbalances, such as low progesterone or high estrogen, can disrupt the normal flow of your menstrual cycle. This can happen due to various reasons, including stress, diet, or other underlying conditions.

What to do: If you suspect a hormonal imbalance, consult with a healthcare provider who can order tests to determine your hormone levels and recommend treatments if necessary.


12. Illness or Infection

How it affects: A serious illness or an infection (such as a pelvic infection or sexually transmitted infection) can affect your reproductive system and cause irregular periods.

What to do: If you suspect an illness or infection, consult your healthcare provider for a proper diagnosis and treatment.


When to See a Doctor:

If your period is late and you have ruled out pregnancy, and if you have any of the following concerns, it’s a good idea to see a healthcare provider:

Your period has been irregular for several months.

You’re experiencing extreme pain, abnormal bleeding, or other unusual symptoms.

You’re under a lot of stress or have significant lifestyle changes that could affect your cycle.

You’ve recently stopped or started birth control or other medications.

A doctor can help identify the underlying cause of your delayed period and recommend appropriate treatment or lifestyle changes.

If your period doesn't come within a few weeks of its expected date and you’re not pregnant, it’s important to seek medical advice to rule out potential health issues.
