The main sign of amenorrhea is the absence of menstrual periods. Depending on the cause of amenorrhea, you might experience other signs or symptoms along with the absence of periods, such as:

Milky nipple discharge
Hair loss
Headache
Vision changes
Excess facial hair
Pelvic pain
Acne Natural amenorrhea

During the normal course of your life, you may experience amenorrhea for natural reasons, such as:

Pregnancy
Breast-feeding
Menopause Contraceptives

Some women who take birth control pills may not have periods. Even after stopping oral contraceptives, it may take some time before regular ovulation and menstruation return. Contraceptives that are injected or implanted also may cause amenorrhea, as can some types of intrauterine devices.

Medications

Certain medications can cause menstrual periods to stop, including some types of:

Antipsychotics
Cancer chemotherapy
Antidepressants
Blood pressure drugs
Allergy medications
Lifestyle factors

Sometimes lifestyle factors contribute to amenorrhea, for instance:

Low body weight. Excessively low body weight — about 10 percent under normal weight — interrupts many hormonal functions in your body, potentially halting ovulation. Women who have an eating disorder, such as anorexia or bulimia, often stop having periods because of these abnormal hormonal changes.
Excessive exercise. Women who participate in activities that require rigorous training, such as ballet, may find their menstrual cycles interrupted. Several factors combine to contribute to the loss of periods in athletes, including low body fat, stress and high energy expenditure.
Stress. Mental stress can temporarily alter the functioning of your hypothalamus — an area of your brain that controls the hormones that regulate your menstrual cycle. Ovulation and menstruation may stop as a result. Regular menstrual periods usually resume after your stress decreases.
Hormonal imbalance

Many types of medical problems can cause hormonal imbalance, including:

Polycystic ovary syndrome (PCOS). PCOS causes relatively high and sustained levels of hormones, rather than the fluctuating levels seen in the normal menstrual cycle.
Thyroid malfunction. An overactive thyroid gland (hyperthyroidism) or underactive thyroid gland (hypothyroidism) can cause menstrual irregularities, including amenorrhea.
Pituitary tumor. A noncancerous (benign) tumor in your pituitary gland can interfere with the hormonal regulation of menstruation.
Premature menopause. Menopause usually begins around age 50. But, for some women, the ovarian supply of eggs diminishes before age 40, and menstruation stops.
Complications
Complications of amenorrhea may include:

Infertility. If you don't ovulate and have menstrual periods, you can't become pregnant.
Osteoporosis. If your amenorrhea is caused by low estrogen levels, you may also be at risk of osteoporosis — a weakening of your bones.
