When experiencing non-menstrual bleeding, what should be checked first along with the possibility of pregnancy?

Rather than whether the blood is brown, the possibility of pregnancy, one-sided pelvic pain, shoulder pain, dizziness, new bleeding after menopause, or repeated bleeding after intercourse will first determine the next course of action. If the possibility of pregnancy is accompanied by one-sided pain, shoulder pain, or dizziness, or if bleeding continues to the point where you must change menstrual products every hour, please be evaluated immediately without waiting for your next appointment. Bleeding after menopause requires medical evaluation even if the amount is small, and if bleeding after intercourse repeats, please check with the timing of the bleeding and your most recent cervical screening results.

When did it start, and what else has changed?

If you have bleeding when it is not your period, first check your last menstrual period, the possibility of pregnancy, the amount of bleeding, and the location of any pain. If there is a possibility of pregnancy accompanied by one-sided pelvic pain, shoulder pain, or dizziness, or if bleeding continues to the point where you must change menstrual products every hour, you must be evaluated immediately rather than waiting for your next appointment.

  • If there is new bleeding after menopause: seek medical evaluation even if the amount is small

Details reviewed during Korean medicine treatment

For bleeding that occurs outside of the menstrual period, we first check for the possibility of pregnancy, changes in the uterus or cervix, and current medications. While investigating the cause, Korean herbal medicine treatment can simultaneously address dizziness, fatigue following bleeding, and the recovery of the menstrual cycle.

Current discomfort

Rather than interpreting the color, record the start time, frequency of changing menstrual products, presence of blood clots, dizziness, shortness of breath, and the relationship with sexual intercourse or medication.

Remaining issues during the recovery period

Observing how symptoms have disrupted your daily life

How to describe my symptoms during the appointment

Discomfort that persists after tests and treatment

When non-menstrual bleeding occurs, what should be checked first along with the possibility of pregnancy?

Rather than whether the blood is brown, the possibility of pregnancy, one-sided pelvic pain, shoulder pain, dizziness, new bleeding after menopause, or repeated bleeding after intercourse will first determine the next course of action. If the possibility of pregnancy is accompanied by one-sided pain, shoulder pain, or dizziness, or if bleeding continues to the point where you must change menstrual products every hour, please be evaluated immediately without waiting for your next appointment. Bleeding after menopause requires medical evaluation even if the amount is small, and if bleeding after intercourse repeats, please check with the timing of the bleeding and your most recent cervical screening results.

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.

Frequently Asked Questions

Frequently Asked Questions Before Your Visit

If I see a small amount of brown blood after my period ends, is that abnormal uterine bleeding?

This may be considered bleeding that occurs outside of your scheduled period. Record whether it ends after a single small amount or if it recurs in relation to sexual intercourse or changes in contraception, and seek medical evaluation if it continues.

Can eating foods that are good for abnormal uterine bleeding stop the bleeding?

Specific foods do not treat the cause or stop bleeding. Heavy bleeding and Anemia symptoms require testing and cause-specific treatment first; diet is intended to support recovery.

If a pregnancy test is negative, is it okay to wait?

A test may be negative if it is taken too early. If you experience bleeding after a delayed period along with pelvic pain or a feeling of fainting, do not wait based on a single result; seek an evaluation on the same day.

Is a pregnancy test always required for abnormal uterine bleeding?

For those of reproductive age with a possibility of pregnancy, this is a primary screening test. If bleeding and pain are present, the possibility of an ectopic pregnancymiscarriage is evaluated along with symptoms and additional tests.

Guidance based on your symptoms

Condition GuidanceAbnormal Uterine BleedingAbnormal uterine bleeding is bleeding that occurs at a different time, amount, or duration than your expected period. This includes spotting between periods or after intercourse, bleeding that lasts more than 7 days, sudden significant changes in cycle, and postmenopausal bleeding. If there is a possibility of pregnancy and you have both bleeding and pelvic pain, or if you soak through a sanitary product every hour for more than 2 hours accompanied by dizziness, shortness of breath, or chest pain, an emergency evaluation takes priority over a consultation regarding the cause.Condition GuidanceImplantation BleedingImplantation bleeding is a common term for light bleeding that may occur around the time a fertilized egg attaches to the uterine lining. A small amount of pink, brown, or red blood may appear on underwear or tissue about 1 to 2 weeks after fertilization, but bleeding cannot be confirmed as implantation based on color, amount, or duration alone. Early pregnancy bleeding also occurs due to cervical changes, infections, early pregnancy loss, or ectopic pregnancy. If there is a possibility of pregnancy or a positive pregnancy test, notify the obstetrics and gynecology clinic of the bleeding and confirm the pregnancy location and progress via blood hCG and ultrasound as needed. Severe pelvic pain on one side, shoulder pain, dizziness, fainting, or heavy bleeding require immediate emergency evaluation.Condition GuidanceThreatened MiscarriageThreatened abortion refers to a state where there is bleeding or pain in early pregnancy, but the pregnancy is progressing on ultrasound. Spotting, red bleeding, or lower abdominal cramping may occur, 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.Condition GuidanceMenopause · PostmenopauseIn healthy individuals aged 45 or older, menopause or the menopausal transition is typically determined clinically without blood tests if symptoms such as hot flashes and menstrual changes are typical. FSH is considered limitedly for suspected symptoms in those aged 40 to 45 or suspected premature ovarian failure in those under 40; values are difficult to interpret during hormonal contraception or treatment. Other causes such as pregnancy possibility or thyroid issues are tested according to the situation, and postmenopausal bleeding must be medically evaluated.Women's Health ColumnWhen menstrual flow increases, how are the causes and treatments of excessive bleeding categorized?Excessive bleeding is not just a matter of the number of menstrual products used. By looking at the extent to which bleeding disrupts daily life, anemia, pain, and causes such as uterine fibroids or adenomyosis, the role of necessary examinations and Korean medicine treatment becomes apparent.Women's Health ColumnMenstrual calendar: Besides the start date, what else should I track to help with treatment?Menstrual records are not a homework assignment to fill in blanks. The direction of examinations and Korean medicine treatment becomes clear only when you record the sequence in which bleeding and pain begin, the discomfort remaining after painkillers, and the recovery process after menstruation ends.
