Why Do Periods Come Late?

Published in Menstrual Cycle 2 mins read

Periods can be late for several reasons, with some being more common than others. Understanding these causes can help you better manage your menstrual cycle. According to provided reference, here's a breakdown of the reasons:

Common Causes of Late Periods

The provided reference outlines some of the most common reasons for a late period:

  • Pregnancy: This is perhaps the most well-known reason. If there's a possibility of pregnancy, taking a pregnancy test is crucial.
  • Stress: High levels of stress can disrupt the hormones that regulate your menstrual cycle, causing delays or even missed periods.
  • Perimenopause: This is the transitional phase leading up to menopause, usually occurring between the ages of 45 and 55. During perimenopause, hormonal fluctuations can lead to irregular periods.

Other Factors That May Contribute to Late Periods

While the provided reference lists the most common reasons, other factors could also contribute to delayed menstruation:

  • Significant Weight Changes: Both drastic weight loss and weight gain can affect your cycle.
  • Excessive Exercise: Overdoing physical activity can sometimes lead to late or missed periods.
  • Medical Conditions: Underlying health issues such as thyroid problems or polycystic ovary syndrome (PCOS) can disrupt your cycle.
  • Hormonal Imbalances: Other hormonal fluctuations not related to perimenopause can also impact your period's timing.
  • Medications: Certain medications, including some antidepressants and birth control pills, may cause irregularities in your cycle.

When to Consult a Doctor

While an occasional late period is often nothing to worry about, it's important to seek medical advice if:

  • Your periods are consistently irregular.
  • You have additional symptoms such as severe pain, heavy bleeding, or unusual discharge.
  • You suspect you might be pregnant.
  • You are experiencing significant emotional or physical distress due to your cycle irregularities.

Understanding your cycle and tracking any changes is key to recognizing irregularities and knowing when to seek help.
