A late period can be a source of anxiety, with pregnancy often being the first concern that comes to mind. However, numerous other factors can cause menstrual irregularities. Understanding these reasons can help alleviate unnecessary worry and allow women to monitor their reproductive health better. Here are 8 common causes of delayed period aside from pregnancy;
- Stress; Elevated stress levels can disrupt the hormonal balance that regulates menstruation. Chronic stress activates the hypothalamic-pituitary-adrenal (HPA) axis, which can interfere with the normal production of reproductive hormones. This disruption may delay or even prevent ovulation, leading to a late or missed period.
- Extreme weight changes; Significant weight loss or gain can affect the menstrual cycle. Dramatic weight loss can lead to amenorrhea (absence of menstruation) by disrupting the body’s hormone production. Conversely, rapid weight gain can cause an increase in estrogen levels, which may result in irregular periods.
- Polycystic Ovary Syndrome (PCOS); PCOS is a hormonal disorder characterized by enlarged ovaries with small cysts. This condition can cause irregular menstrual cycles due to hormonal imbalances, particularly elevated levels of androgens (male hormones). Women with PCOS may experience infrequent, prolonged, or unpredictable periods.
- Hormonal contraceptives; Starting, stopping, or changing hormonal birth control methods can cause menstrual irregularities. It may take several months for the body to adjust to new hormone levels, potentially resulting in late or missed periods. This is especially common when discontinuing hormonal contraceptives.

- Perimenopause; As women approach menopause, typically in their 40s or early 50s, hormonal fluctuations can cause irregular periods. Perimenopause is characterized by declining estrogen levels, which can lead to longer or shorter cycles, skipped periods, or changes in menstrual flow.
- Intense exercise; Excessive physical activity, particularly in athletes or those who exercise intensively, can lead to amenorrhea. This condition, known as exercise-induced amenorrhea, occurs when the body doesn’t produce enough estrogen to complete the menstrual cycle due to low body fat percentage and high energy expenditure.
- Certain medications; Some medications can affect menstrual regularity. These may include antidepressants, antipsychotics, chemotherapy drugs, and corticosteroids. These medications can influence hormone levels or disrupt the normal functioning of the hypothalamus and pituitary gland, which control the menstrual cycle.
- Chronic diseases; Various chronic conditions can impact menstrual regularity. Diseases such as diabetes, celiac disease, and uncontrolled inflammatory bowel diseases (like Crohn’s disease or ulcerative colitis) can affect hormone production and metabolism, potentially leading to irregular or missed periods.
In conclusion, it’s important to remember that every woman’s body is unique. Occasional irregularities in your cycle are often normal, but persistent changes or concerns should always be discussed with a healthcare provider.
