Periods stopped for no reason

A missed period is a symptom, not a diagnosis. Pregnancy should be considered whenever it is possible. Other explanations include major stress, changes in weight or exercise, illness, thyroid problems, medication effects, polycystic ovary syndrome, menopause, or reduced ovarian function. Some people have no obvious trigger until a clinician reviews the history and test results.

The timing matters: age, previous cycle pattern, contraception, breastfeeding, pelvic symptoms, and family history can all change the assessment. A pregnancy test and selected blood tests may be appropriate.

If pregnancy is possible, take a home test according to its instructions and arrange care if the result is positive, unclear, or your period remains absent. Write down your last period, recent stress or illness, weight or exercise changes, medicines, and symptoms such as hot flushes, acne, or excess hair growth. Avoid taking hormones borrowed from someone else.

Seek urgent help for a positive pregnancy test with severe pain, heavy bleeding, faintness, or shoulder-tip pain. Arrange a routine appointment for repeated missed periods, new pelvic pain, milky nipple discharge, headaches with vision changes, or symptoms suggesting menopause or ovarian insufficiency. Do not wait for a pattern to become severe.

Ask which causes fit your age and history, whether you need pregnancy or hormone testing, how long to monitor, and how absent periods may affect fertility or bone health. Ask what symptoms should prompt urgent review.
