There are many reasons for missing a period besides pregnancy. Common causes include stress , which can disrupt the hormones regulating the menstrual cycle; weight changes such as sudden weight loss or gain; birth control use, especially hormonal contraceptives; and medical conditions like polycystic ovary syndrome (PCOS) , thyroid problems , and other chronic illnesses. Additionally, natural life stages such as adolescence, perimenopause, and menopause can cause irregular or missed periods. Excessive exercise, breastfeeding, and certain medications can also affect the timing of your period. It is often nothing to worry about, but if periods miss repeatedly or are accompanied by other symptoms, consulting a healthcare professional is advisable for diagnosis and treatment.
