Connecting Implantation Bleeding to Your Symptoms
Focus on the possibility of pregnancy and pain rather than whether the blood is brown or bright red
Record the start date of your last menstrual period, the date of intercourse or embryo transfer, the date and result of your pregnancy test, and the time, amount, and duration of the bleeding. Brown blood may simply be old blood and is not a color that confirms implantation bleeding. Do not self-diagnose pregnancy simply because the timing is similar to your expected period.
Early pregnancy bleeding may require repeating necessary tests at specific intervals
In very early pregnancy, a single ultrasound or pregnancy hormone test may not clearly show the location or progress. Repeat tests at the time guided by your medical provider, and notify them immediately if bleeding or pain changes. One-sided pelvic pain, shoulder pain, or dizziness that feels like fainting must be promptly evaluated, including for the possibility of an ectopic pregnancy.
The role of Korean herbal medicine is determined only after pregnancy status is confirmed
Once the location and progress of the pregnancy are confirmed and there are no urgent risks, we examine symptoms that disrupt daily life, such as nausea, loss of appetite, tension making it difficult to sleep, feeling cold, mild lower back pain, or fatigue. If necessary, the scope of Korean herbal medicine treatment is determined within the framework of the OB-GYN's tests and medication plan; it is not described as a treatment that guarantees a pregnancy outcome. After treatment, changes in bleeding and pain are monitored according to the OB-GYN's plan, while recovery of daily life, such as food intake, sleep, and energy levels, is recorded separately.

- Condition GuideImplantation 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 it cannot be confirmed as implantation bleeding based on color, amount, or duration alone. Early pregnancy bleeding also occurs due to changes in the cervix, infections, early pregnancy loss, or ectopic pregnancy. If there is a possibility of pregnancy or a pregnancy test is positive, notify your gynecologist of the bleeding and, if necessary, confirm the location and progress of the pregnancy via serum hCG and ultrasound. Severe pelvic pain on one side, shoulder pain, dizziness, fainting, or heavy bleeding require immediate emergency evaluation.→
- Condition GuideThreatened MiscarriageThreatened miscarriage refers to a state where there is bleeding or pain in early pregnancy, but the ultrasound shows the pregnancy is still progressing. This may include spotting, red bleeding, or 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.→
- Medical Evaluation GuideWhat should I check first when menstrual pain and bleeding change?First, check if the pain is more severe than usual, if bleeding has increased or occurred between periods, or if there is a possibility of pregnancy. If you experience bleeding that requires changing menstrual products every hour, dizziness as if you might faint, shortness of breath, or if you have one-sided pelvic pain, shoulder pain, and bleeding along with a possibility of pregnancy, you must be evaluated immediately without waiting for your next appointment. If it is not an urgent situation, please record not only the pain level but also any preceding changes, such as a feeling of blockage in the solar plexus, constipation, or cravings for sweets before menstruation, to help narrow down the treatment questions more quickly.→
