lateperiod

Late period refers to the onset of menstruation later than the expected day in a person’s typical menstrual cycle. Most people have cycles that range from about 21 to 35 days; a period that arrives more than seven days after the predicted date is commonly described as late. A single late period can be a normal variation, particularly during adolescence or in the years leading up to menopause, while recurrent lateness may indicate an underlying issue.

Common causes include pregnancy, which is the most frequent reason for a late period. Hormonal fluctuations related to puberty, perimenopause, or changes in hormonal contraception can also delay menses. Other factors that can delay a period include stress, significant weight loss or gain, intense exercise, and illness. Medical conditions such as thyroid disorders or polycystic ovary syndrome (PCOS), as well as certain medications that affect hormones, can contribute as well. Less commonly, uterine or pituitary problems can affect cycle timing.

Evaluation typically begins with a home pregnancy test. If the test is negative and late periods persist, medical assessment may be advised. A clinician may review menstrual history, perform a physical examination, and order laboratory tests (for example, thyroid function, prolactin, or other hormone levels) or imaging studies to identify contributing conditions.

Management depends on the cause. If pregnant, prenatal care is indicated. If non-pregnant, treatment may focus on addressing the underlying condition or on regaining regular cycles, which can involve lifestyle adjustments, hormonal therapies, or changes in contraception. Recurrent or unresolved late periods warrant professional evaluation, especially when associated with very heavy bleeding, severe pain, or other concerning symptoms.
