Changes in the menstrual cycle can be caused by various factors. If menstruation is delayed by 15 days, common reasons include:
1. Pregnancy: This is one of the most common causes. If you have had sexual intercourse and did not use effective contraception, pregnancy should be considered first.
2. Stress: Prolonged mental tension, anxiety, or excessive stress can affect the function of the hypothalamic-pituitary-ovarian axis, leading to changes in the menstrual cycle.
3. Dietary disturbances: Irregular eating habits, malnutrition, or excessive weight loss may affect hormonal balance and lead to irregular menstruation.
4. Lifestyle factors: Excessive fatigue, lack of sleep, or chronic late-night activities and other unhealthy lifestyle habits may also affect the menstrual cycle.
5. Medication effects: Certain medications, such as antibiotics, antidepressants, and hormonal drugs, may also cause changes in the menstrual cycle.
6. Age: During early puberty and around menopause, due to natural fluctuations in hormone levels, menstrual cycles may become irregular.
7. Medical conditions: Gynecological disorders such as polycystic ovary syndrome (PCOS) and endometriosis can cause menstrual irregularities and delays.
