Amenorrhea Symptom Check Quiz

Amenorrhea means the absence of menstrual periods. Primary amenorrhea is when periods have not started by age 15. Secondary amenorrhea is when periods stop for three months or longer after they previously occurred.

Primary amenorrhea means periods have never started by age 15. Secondary amenorrhea means periods stop for three months or longer after previously being regular. Both types can involve hormone signaling, but primary amenorrhea may also involve developmental, structural, or genetic factors.

Missed periods can be a sign that ovulation or hormone signaling has changed. Evaluation can help identify pregnancy, thyroid problems, PCOS, prolactin changes, low estrogen, ovarian concerns, or lifestyle-related hormone stress. Finding the cause can also help protect bone health and fertility planning.

Amenorrhea can be caused by pregnancy, stress, intense exercise, low body weight, eating disorders, PCOS, thyroid disorders, high prolactin, premature ovarian insufficiency, some medications, or structural reproductive differences. Primary amenorrhea may also involve delayed puberty or genetic conditions.

See a doctor if you are 15 or older and have never had a period. Also seek care if you miss three consecutive periods and are not pregnant. Early evaluation can help identify causes and reduce risks such as bone loss.

Some people have no other symptoms. Others may notice hot flashes, night sweats, vaginal dryness, acne, increased facial or body hair, scalp hair thinning, breast milk discharge, headaches, vision changes, weight changes, or mood and energy changes.

Diagnosis usually starts with a medical history, physical exam, and pregnancy test. A clinician may ask about menstrual history, medications, exercise, weight changes, stress, and symptoms. Blood tests and imaging may be used depending on the suspected cause.

Blood tests often include estradiol, follicle-stimulating hormone, luteinizing hormone, prolactin, and thyroid hormones. Low estradiol may point to hypoestrogenic amenorrhea from hypothalamic, pituitary, or ovarian causes. These tests help guide the next steps, but they do not diagnose every cause alone.

Rite Aid can connect users with blood testing options that include fertility-related hormones such as estradiol. Results may help support a conversation with a healthcare professional about missed periods, ovulation, and possible next steps.

Yes, if pregnancy is possible, a pregnancy test is usually the first step because pregnancy is the most common reason periods stop. If a test is positive, unclear, or paired with pain or bleeding, seek medical guidance promptly.

Yes, low estrogen levels from some forms of amenorrhea can weaken bones over time. Estrogen helps maintain bone density. If periods are absent for months, it is worth discussing bone health and hormone evaluation with a healthcare professional.

Yes, chronic stress can disrupt brain signals that help control the menstrual cycle. Stress hormones may interfere with reproductive hormones, which can pause ovulation and menstruation. Stress management may help, but persistent missed periods should still be evaluated.

Yes, low body weight, low body fat, eating restriction, and intense exercise can reduce the energy available for normal hormone production. This is common in athletes and people with eating disorders. Medical and nutrition support may be needed to restore cycles safely.

Some people experience delayed return of periods after stopping hormonal birth control. Periods often return within three to six months. If they do not, consider speaking with a clinician to check for underlying hormone issues that may have been masked by birth control.

Amenorrhea often means ovulation is not happening regularly, so pregnancy may be harder while periods are absent. Many causes are treatable. Identifying the cause and restoring healthier cycle patterns may improve fertility planning.
