Should I take a pregnancy test first if my period doesn't come?

If sexual activity is possible, pregnancy should be confirmed first, regardless of whether contraception was used. Even if the result is negative, please re-test with a medical professional if the test was taken too early or if the absence of menstruation continues.

What should I record along with symptoms of amenorrhea?

In addition to when menstruation was delayed or stopped, record changes in weight, amount of exercise, stress, hirsutism, skin changes, and medications you are taking. If menstruation is missed after sexual activity, perform a pregnancy test first. If severe pain in one side of the lower abdomen, bleeding, dizziness, or fainting occurs, the possibility of an ectopic pregnancy must be promptly evaluated.

What is the first step in testing for amenorrhea?

If pregnancy is possible, a pregnancy test is performed first. Afterward, the timing of the start of menstruation, changes in cycle, weight changes, exercise, stress, medications, and accompanying symptoms are checked. Based on the examination results, necessary tests such as hormone, thyroid-related, or imaging tests are selected. A single test cannot distinguish all causes.

If you are in this situation

Do not simply wait it out; let's first discuss the reason why menstruation has stopped

If you are repeatedly taking only pregnancy tests every time a due date passes, or attributing it to weight, exercise, or stress, you must first check for pregnancy and causes related to hormones, nutrition, and ovarian function.

Discomfort that persists after tests and treatment

Do not simply wait and see why your menstruation has stopped; let's discuss it first.

While gynecological examinations and necessary causal treatments are prioritized, remaining pain, the burden of bleeding, sleep, digestion, and decreased energy during the treatment process are not dismissed as trivial issues. Changes before and after treatment and their cycles are monitored on the same timeline.

We establish a recovery sequence by dividing the roles of existing treatments and Korean herbal medicine treatment. If there is a cause that needs to be treated first, that treatment is continued. Korean herbal medicine treatment determines the primary goal and progress criteria by examining the remaining symptoms, their impact on daily life, and the patterns in which sleep, digestion, body heat, and fatigue move together based on those results. The sequence of combining it with existing treatments is adjusted according to actual responses, and lifestyle management is tailored to support the treatment goals.

Understanding the diagnosis and test results

Amenorrhea: Checking for pregnancy first, then dietary, exercise, and hormonal causes

amenorrheaThe first cause to check is pregnancy. If not pregnant, causes may include physiological changes such as breastfeeding or menopause, rapid weight loss, insufficient energy intake, excessive exercise, stress, polycystic ovary syndrome (PCOS), thyroid/hypothalamic/pituitary issues, primary ovarian insufficiency, hormonal contraceptives, or other medications. If the first period has not yet started, delayed puberty, genetic/chromosomal conditions, and differences in uterine or vaginal development are also checked. Rather than attributing the cause to weight or stress alone, we differentiate the cause through pregnancy tests, medical history, physical examinations, and necessary hormone tests or ultrasounds.

How will my treatment be divided?

Concurrent Treatment

After identifying the reason why menstruation stopped, we simultaneously monitor the recovery of your cycle and overall physical condition.

We first proceed with tests and treatments to identify the cause of bleeding and pain. When combining this with Korean medicine treatment, we specifically define the remaining discomforts among fatigue, dizziness, or poor sleep following the cycle changes and bleeding.

In Korean medicine treatment,

we examine recurring symptoms and the body's recovery

While addressing identified causes such as nutritional deficiency, excessive exercise, stress, PCOS, or ovarian function, we also monitor the recovery of sleep, digestion, body temperature (cold/heat), weight, and pre- and post-menstrual symptoms.

Integrated Treatment

Test, medication, and procedure schedules are shared as they are

While maintaining nutritional, hormonal, or metabolic treatment, we can provide supportive care for the recovery of sleep, digestion, body temperature (cold/heat), and general energy.

We simultaneously check the possibility of pregnancy, age, and previous cycles

The timing for fertility counseling is moved forward depending on age, the duration of amenorrhea, ovarian function, and pregnancy plans.

Cases requiring an OB/GYN evaluationCheck when applicable

The possibility of pregnancy is checked first; severe headaches, vision changes, milky nipple discharge, rapid weight changes, flushing, or pelvic pain are evaluated without delay.

Possibility of pregnancy and severe pain in the lower abdomen on one side
Vaginal bleeding with severe dizziness, fainting, or paleness
Sudden severe headache, vision changes, or changes in consciousness
Severe dietary restriction, dehydration, or rapid physical weakness

Surgery, procedure, or further evaluationConsultations for procedures or surgery related to the specific cause are provided only when structural problems in the uterus or ovaries are confirmed.

To what extent to integrate Korean medicine treatment

Amenorrhea: Distinguishing the roles of the two treatments

We first check the duration of the absence of menstruation, the possibility of pregnancy, weight changes, exercise, and thyroid and ovarian functions. While continuing necessary evaluations and treatments, we simultaneously monitor sleep, digestion, energy levels, and cycle changes.

Current discomfort

Observing how symptoms have disrupted your daily life

Please record the date of your last menstrual period and the date of your pregnancy test, and mark when there were changes in weight, diet, exercise, sleep, stress, or medications.

Differences in prescription

Categorizing symptom combinations even within the same diagnosis

Prescription priorities are determined by selecting clues from the following patterns that match the actual medical interview and examination: Qi and Blood deficiency, nutritional deficiency, Kidney deficiency, ovarian dysfunction, dampness-phlegm/ovulation stagnation, or Qi stagnation and Blood stasis/stress.

Evaluating effectiveness

Re-evaluating through the next cycle and lifestyle changes

We do not look only at the presence or absence of menstruation, but also monitor whether energy intake, weight stability, hot flashes, sleep, ovulation/examination plans, and bone health evaluations are proceeding in a timely manner.

Treatment goalRather than aiming to force menstruation, we identify the cause and track changes in the body's recovery process while protecting reproductive, metabolic, and bone health.

Understanding Tests and Diagnosis

Amenorrhea: Three things to know first

When Interpreting Test Results

If there is a possibility of sexual activity, pregnancy is confirmed first regardless of contraceptive use.

When Identifying Causes and Risk Factors

Along with weight, eating habits, exercise, and stress, PCOScauses related to the thyroid, ovaries, pituitary gland, and medications are checked together.

When Reviewing Lifestyle Changes

If severe abdominal pain, dizziness, fainting, or bleeding overlap with the possibility of pregnancy, ectopic pregnancy is immediately ruled out.

Defining the role of concurrent treatment

Integrating tests, procedures, and Korean medicine treatment within a single plan

Scheduled tests and procedure dates are shared

We do not arbitrarily change the current plan and instead record symptoms and recovery status before and after treatment.

Setting specific goals for Korean medicine treatment

While evaluating causes related to pregnancy, endocrine system, nutrition, and ovarian function, if decreased intake, excessive exercise, hot flashes, or sleep problems persist alongside the cessation of menstruation, the burden of recovery is distributed within a range that does not interfere with the treatment of the cause.

Review all medications in a single list

Please provide a complete list of prescription drugs, over-the-counter drugs, Korean herbal medicine, and supplements to adjust the timing and feasibility of concurrent use.

What to prepare before your visit

Please organize these three things before your visit

Date of last menstrual period and cycles over the previous 12 months

Note the test dates and results together to track recent changes.

Results for pregnancy, thyroid, prolactin, FSH, estradiol, and ultrasound

Prepare test results and a list of medications used so that the status before and after treatment can be compared.

Weight, diet, amount of exercise, sleep, stress, and all current medications

Inform the medical staff of all prescription drugs, over-the-counter drugs, Korean herbal medicine, and supplements without omission.

Director Choi Yeon-seung's Clinical Perspective

Menstrual records have been empty for three months; what will be checked during the medical evaluation?

In the consultation room, the first things checked are the date of the last menstrual period and the cycle over the previous 12 months. Subsequently, results for pregnancy, thyroid, prolactin, FSH, estradiol, and ultrasound, as well as current medications, are reviewed to determine the goals and timing of Korean medicine treatment so as not to interfere with existing tests or prescriptions.

Changes to be confirmed in this treatmentItems to be reviewed again after treatment include the last menstruation, changes in intake and exercise, and the hormone and bone health schedule.

When continuing the two treatments together

Amenorrhea: Four symptom combinations for prescribing Korean herbal medicine

Pregnancy, thyroid, prolactin, PCOS, hypothalamic amenorrhea·Diminished Ovarian ReserveAfter ruling these out, we categorize clues into Qi and Blood deficiency, Kidney deficiency, Phlegm-Dampness, and Qi stagnation and Blood stasis.

Pattern identification (Byun-jeung) is not about renaming a gynecological diagnosis. For each condition, we determine whether to center the care on Korean medicine treatment, combine it with other treatments, or prioritize treating the underlying cause first. Then, we reflect items that actually change together, such as cycle, pain, cold/heat sensations, digestion, sleep, and energy levels, into the prescription.

Qi and Blood Deficiency / Nutritional Deficiency Type

When menstruation stops along with fatigue following weight loss or excessive exercise

Changes observed in cycles and pain: We look at weight changes, intake, exercise volume, and low secretion levels.
Concurrent changes observed in the body: We check for dizziness, sensitivity to cold, hair loss, decreased concentration, and eating disorder risks.
Prescription Priority: We help recover Qi and Blood, focusing on nutritional and exercise adjustments and professional evaluation.

Kidney Deficiency / Ovarian Function Decline Type

When amenorrhea overlaps with hot flashes, night sweats, and vaginal dryness

Changes observed in cycles and pain: We look for amenorrhea following a shortened cycle, heat sensations, and dryness.
Concurrent changes observed in the body: We check FSH, estradiol, AMH, family history, and treatment history.
Prescription Priority: We maintain hormone and bone health plans while simultaneously focusing on sleep and systemic recovery.

Phlegm-Dampness / Ovulation Stagnation Type

When acne, hirsutism, weight changes, and oligomenorrhea (infrequent periods) occur together

Changes observed in cycles and pain: We examine long cycles, ovulation clues, and metabolic indicators.
Concurrent changes observed in the body: We check for risks of PCOS, blood glucose, lipids, and sleep apnea.
Prescription Priority: We maintain a plan for metabolism and endometrial protection while adjusting for signs of dampness-phlegm.

Qi stagnation and blood stasis / Stress-type

When the cycle stops along with a feeling of tightness in the lower abdomen after significant stress

Changes observed in cycles and pain: We check if only premenstrual sensations repeat without actual bleeding.
Concurrent changes observed in the body: We first rule out pregnancy and endocrine causes, then check sleep, digestion, and tension levels.
Prescription Priority: After evaluating the cause, we prioritize resolving congestion and restoring life rhythms.

Order of Prescription Adjustment

Check for urgent medical evaluation and current treatments
Check for emergency symptoms and the timing for re-evaluation; do not arbitrarily change prescription or procedure plans.
Select the combination of symptoms that actually recur
Rather than using the four categories as a self-diagnosis checklist, we retain only the relevant clues from medical interviews and existing tests.
Determine the next prescription based on the same items
We re-verify the date of the last period, dietary intake, changes in exercise, hormones, and bone health schedules to decide whether to maintain, adjust, or discontinue treatment.

We review pregnancy-related evaluations, tests or surgeries for structural diseases, antibacterial treatment for infections, and schedules for infertility procedures and menopause treatment to divide and coordinate the scope of Korean herbal medicine treatment. Treatment goals are tracked by specifically defining changes in pain, bleeding, sleep, energy levels, and daily functioning.

Additional information to know regarding amenorrhea

You can check a brief definition before proceeding to a detailed explanation.

AmenorrheaAmenorrhea is a state where menstruation has not started or where previous menstruation has stopped for a certain period.OvulationOvulation is the process where an egg is released from the ovary. Because the date can vary with each menstrual cycle, it is difficult to determine the exact ovulation date through calendar calculation alone.Menstrual CycleThe menstrual cycle is the period from the first day of one menstruation to the day before the next menstruation begins.

Frequently Asked Questions

Frequently Asked Questions about amenorrhea

If my period doesn't come, should I take a pregnancy test first?

If sexual activity is possible, confirm pregnancy first regardless of contraceptive use. Even if the result is negative, re-test with medical staff if the test was taken too early or if the absence of menstruation continues.

Can dieting and exercise cause amenorrhea?

Rapid weight loss, insufficient intake, and excessive exercise can suppress hormonal function, but other causes must also be evaluated.

Can taking contraceptive pills cause menstruation to stop?

Some hormonal contraceptive methods reduce or stop bleeding. Do not discontinue them arbitrarily; confirm the possibility of pregnancy, the type of medication, and the dosage method with your prescriber.

What should I record along with amenorrhea symptoms?

In addition to when the period was delayed or stopped, record weight changes, amount of exercise, stress, hirsutism, skin changes, and medications taken. If a period is missed after sexual activity, take a pregnancy test first. If accompanied by severe pain in one side of the lower abdomen, bleeding, dizziness, or fainting, the possibility of an ectopic pregnancy must be promptly evaluated.

What tests are done first for amenorrhea?

If pregnancy is possible, a pregnancy test is performed first. Afterward, we check the onset of menstruation, cycle changes, weight changes, exercise, stress, medications, and accompanying symptoms. Based on the examination results, necessary tests such as hormone, thyroid-related, or imaging tests are selected. A single test cannot identify all causes.

When can Korean herbal medicine treatment be considered for amenorrhea?

This is possible. We share the existing schedule for tests, medications, and procedures, and first determine what will be evaluated through Korean medicine treatment. While ensuring that identified causes such as nutritional deficiency, over-exercise, stress, PCOS, and ovarian function are not overlooked, we simultaneously monitor the recovery of cold/heat sensations, sleep, digestion, weight, and pre- and post-menstrual symptoms.

What should I record before a consultation for amenorrhea?

It is helpful to organize the following information in chronological order: the date of your last menstrual period and cycles for the previous 12 months, results for pregnancy, thyroid, prolactin, FSH, estradiol, and ultrasound, as well as weight, diet, exercise amount, sleep, stress, and all current medications. Please prepare the date of your last menstrual period, test results, and the timing of any changes in weight, diet, or exercise.

Can I use Korean herbal medicine along with amenorrhea treatment?

Do not stop your current prescriptions arbitrarily, and please inform us of all medications and supplements you are taking. Rather than focusing on forcing menstruation, we identify the cause and track changes in the body's recovery process while protecting reproductive, metabolic, and bone health.
