Threatened Miscarriage: Read in the order of your curiosity
Understanding the diagnosis and test results
Threatened Miscarriage: First, verify pregnancy location, fetal heartbeat, bleeding, and follow-up schedule
Threatened miscarriagemiscarriagerefers to a state where bleeding or pain occurs in early pregnancy, but the pregnancy is still progressing as seen on ultrasound. This may range from spotting to red bleeding and lower abdominal cramping, but the outcome cannot be predicted by the amount of bleeding alone. Heavy bleeding, severe one-sided pain, shoulder pain, dizziness, or fainting must be evaluated immediately due to the possibility of ectopic pregnancy and massive hemorrhage.
The scope of Korean medicine treatment is determined after verifying the current pregnancy location, fetal heartbeat, and progress of bleeding.
Even if bleeding is minimal, if the pregnancy location and progress have not yet been confirmed, follow-up at an obstetrics and gynecology (OB/GYN) clinic comes first. Severe one-sided pain, shoulder pain, fainting, or heavy bleeding must be evaluated immediately.
Begin with safety confirmation and treating the cause
Verify the pregnancy location, fetal heartbeat, and progress of bleeding via ultrasound and hCG, and follow the prescribed medications and follow-up plan.
Determine the scope of Korean medicine treatment during the recovery phase
Only when there is no acute risk and medication has been coordinated with the attending medical staff will we limitedly address nausea, poor sleep, or fatigue; we do not promise the outcome of maintaining the pregnancy.
Gestational age, ultrasound results, changes in hCG, history of previous miscarriages, and all current medications determine the timing of the next visit.
Cases requiring an OB/GYN evaluationPlease check first
Severe one-sided pain, shoulder pain, fainting, heavy bleeding, or fever require immediate emergency evaluation. We do not promise the maintenance of pregnancy or the prevention of miscarriage through Korean herbal medicine.
- Heavy bleeding that repeatedly soaks pads in a short period of time
- Severe one-sided pelvic pain or pain at the tip of the shoulder
- Dizziness, fainting, paleness, or shortness of breath
- Fever, chills, or foul-smelling discharge
Surgery, procedure, or further evaluationDepending on the cause, such as ectopic pregnancy, progressive bleeding, or infection, medication or surgical treatment may be necessary, so do not wait for emergency symptoms to worsen.
When initially required treatment is needed
Threatened Miscarriage: Helping recovery after safety is confirmed
For bleeding and pain in early pregnancy, the pregnancy location, fetal heartbeat, and progress must be verified first. While adhering to the follow-up and medications of the attending OB/GYN, we provide limited support for nausea, sleep, and fatigue.
Observing how symptoms have disrupted your daily life
Record the date of the last menstrual period, gestational age, ultrasound, hCG, amount of bleeding, pain, dizziness, and all prescribed medications, vaginal suppositories, and injections in chronological order.
Categorizing symptom combinations even within the same diagnosis
Prescription priorities are determined by selecting the clues that match the actual medical interview and examination among: emergency evaluation priority, OB/GYN follow-up priority, weak digestive system, poor intake, mental/physical anxiety, or sleep-related types.
Re-evaluating through the next cycle and lifestyle changes
The highest priority is given to changes in bleeding, pain, body temperature, and dizziness, as well as ultrasound/hCG follow-ups and adherence to prescribed medications.
Treatment goalWe do not promise pregnancy outcomes and ensure that symptoms requiring primary verification are not missed; we help alleviate discomfort within a scope that does not interfere with OB/GYN follow-ups and medications.
Checking the safety line for bleeding during pregnancy
Priority is given to changes in bleeding, pain, body temperature, and dizziness, as well as ultrasound/hCG tracking and adherence to prescribed medications.

Threatened Miscarriage: Three things to know first
When Interpreting Test Results
Bleeding can vary from pink spotting to brown discharge, bright red bleeding, and blood clots; the progress of the pregnancy cannot be determined by color and amount alone.
When Identifying Causes and Risk Factors
One-sided pelvic pain, pain at the tip of the shoulder, dizziness, or fainting require an emergency OB/GYN evaluation, including the possibility of an ectopic pregnancy.
When Reviewing Lifestyle Changes
Record the time bleeding started, the color, the presence of blood clots, and the pad replacement interval on the heaviest day to provide during your medical evaluation.
Support for digestion, sleep, and energy levels is provided only as a supplement, within the scope permitted by the attending OB/GYN and after the pregnancy location and progress have been confirmed.
Conceptual reference · ACOG: Bleeding During Pregnancy · ACOG: Early Pregnancy LossNecessary initial treatment and recovery period care
Complete the necessary primary treatment first, then continue with Korean medicine treatment during the recovery period.
Adhere to the necessary primary treatment first
Share the test, medication, and re-examination schedule set by your medical staff, and do not change them arbitrarily until the treatment response is confirmed.
The scope of Korean medicine treatment is determined after confirmation
The core of this stage is not persuading the patient to maintain the pregnancy, but rather the OB/GYN tracking of pregnancy location, fetal heartbeat, and bleeding. Support for digestion, sleep, and energy is provided only when permitted by the medical staff and when there is no acute risk.
Re-evaluate immediately if symptoms change
Severe one-sided pain, shoulder pain, fainting, heavy bleeding, or fever require immediate emergency evaluation. We do not promise the maintenance of pregnancy or the prevention of miscarriage through herbal medicine.
What to prepare before your visit
Please organize these three things before your visit
Gestational age, last menstrual period, ultrasound, hCG, and the next follow-up date
Note the test dates and results together to track recent changes.
Amount of bleeding, location of pain, dizziness, shoulder pain, and body temperature
Prepare test results and a list of medications used so that the status before and after treatment can be compared.
Full list of progesterone, vaginal suppositories, injections, aspirin, herbal medicine, and supplements
Inform the medical staff of all prescription drugs, over-the-counter drugs, Korean herbal medicine, and supplements without omission.
Rather than judging by the color of the blood alone, we first examine the pregnancy location, pain, bleeding, and follow-up tests.
Conceptual reference · ACOG: Bleeding During Pregnancy · ACOG: Early Pregnancy LossChanges to monitor before and after treatment
Check again using the same categories to determine if the treatment is helpful
Priority is given to changes in bleeding, pain, body temperature, and dizziness, as well as ultrasound/hCG tracking and adherence to prescribed medications.
Bleeding and Pain
Establish a baseline by confirming your current status during the first consultation.
Ultrasound and hCG
Record this along with the dates when treatment or medication changed.
Adherence to prescribed medications
Look for consistent changes over several days rather than a single good day.
Record not only the start date but also the amount of bleeding, pain, medication, and impact on daily life using the same criteria.
After completing treatment for the cause
Threatened Miscarriage: Four Symptom Combinations for Korean Herbal Medicine Prescriptions
Support for digestion, sleep, and energy is provided only after the pregnancy location and progress have been confirmed and within the scope permitted by the attending obstetrician-gynecologist.
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.
When there is severe one-sided pain, fainting, shoulder pain, or heavy bleeding
- Changes observed in cycles and pain
- We evaluate the amount of bleeding, location of pain, blood pressure, and feelings of fainting.
- Concurrent changes observed in the body
- We immediately evaluate for ectopic pregnancy, hemorrhagic shock, and infection.
- Prescription Priority
- Emergency OB-GYN evaluation is prioritized over Korean herbal medicine.
When the pregnancy location or progress is still uncertain, even with light bleeding
- Changes observed in cycles and pain
- We evaluate the gestational age, ultrasound, hCG changes, and bleeding.
- Concurrent changes observed in the body
- We check prescribed medications, vaginal suppositories, and the follow-up interval.
- Prescription Priority
- The attending obstetrician-gynecologist's plan takes priority without arbitrary changes to prescriptions.
When eating is difficult due to nausea and vomiting after safety has been confirmed
- Changes observed in cycles and pain
- We evaluate intake amount, vomiting, urination, and weight.
- Concurrent changes observed in the body
- We check for dehydration, hyperemesis gravidarum, and medication safety.
- Prescription Priority
- In coordination with the attending physician, we provide limited support only for digestion and energy.
When anxiety and nighttime awakenings worsen following bleeding
- Changes observed in cycles and pain
- We evaluate sleep, heart rate, search behaviors, avoidance, and appetite.
- Concurrent changes observed in the body
- We check for mental health support and a clear follow-up plan.
- Prescription Priority
- We help restore sleep and reduce tension, focusing on explanations regarding the progress of the pregnancy.
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-evaluate changes in bleeding, pain, ultrasound results, hCG levels, and prescription adherence to determine 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.

You can check a brief definition before proceeding to a detailed explanation.Frequently Asked Questions
Frequently asked questions about threatened miscarriage
Is a small amount of spotting a sign of threatened miscarriage?
Early spotting can occur for various reasons. Bleeding during pregnancy must be reported to the obstetrics and gynecology (OB/GYN) clinic to confirm the location and progress of the pregnancy via ultrasound.
Is brown bleeding safe?
Brown discharge may be old blood, but safety cannot be determined by color alone. We check the amount, pain, and the progress of the pregnancy together.
Can I take herbal medicine for threatened miscarriage symptoms?
The pregnancy location, progress, and any prescription medications must first be confirmed by an OB/GYN. Do not take herbal medicine arbitrarily during pregnancy; instead, consult regarding the necessary scope of Korean herbal medicine treatment.
When can herbal medicine treatment be considered for threatened miscarriage?
For this condition, confirming safety and treating the cause come first. Only when there is no acute risk and medication has been coordinated with the attending medical staff will we limitedly address nausea, poor sleep, or fatigue; we do not promise results regarding the maintenance of the pregnancy.
What should I record before a consultation for threatened miscarriage?
It is helpful to organize the following information chronologically: gestational age, last menstrual period, ultrasound and hCG results with the next follow-up date, amount of bleeding, location of pain, dizziness, shoulder pain, body temperature, and a full list of progesterone, vaginal suppositories, injections, aspirin, herbal medicine, and supplements. Please first provide the gestational age, ultrasound/hCG tracking, records of bleeding/pain, and all pregnancy-related medications.
Can I use herbal medicine alongside treatment for threatened miscarriage?
Do not stop your current prescriptions arbitrarily, and please disclose all medications and supplements you are taking. We do not promise pregnancy outcomes and ensure that critical symptoms are not overlooked; we provide support for discomfort within a scope that does not interfere with OB/GYN follow-ups or medication.
