Bleeding during pregnancy


I apologize for the previous inquiries, but they seem to be from over 10 weeks ago.
I am currently 11 weeks pregnant (as of June 5) and experienced sudden heavy bleeding.
I went to the hospital and had an ultrasound, which showed a normal fetal heartbeat, but there were blood clots in the uterus.
The doctor mentioned that the clots would either be absorbed or expelled on their own.
However, a week later (on June 12), I experienced heavy bleeding again and had another ultrasound, which indicated that the blood clots seemed to be larger this time, even bigger than the fetus.
Both times, the outcome was to receive an injection and go home with medication.

I would like to ask why blood clots are forming (I have had one daughter and two previous induced abortions).
Will the blood clots affect the fetus? Should I have regular follow-up examinations? If so, how often should they be scheduled? If not, what precautions should I take? Is sexual intercourse permissible? Regarding diet, what foods can help eliminate blood clots (is it okay to take traditional Chinese medicine)? Thank you for your response.

Dr. Lü Lizheng reply Obstetrics and Gynecology


Why are blood clots forming? It may be caused by partial detachment or rupture of the placenta.
Will the blood clots affect the fetus? Currently, it should not, but if the detachment or rupture expands to more than half of the placental area, it could affect the nutrient supply to the fetus, so caution is advised.
Should regular follow-up examinations be conducted? Monitor the bleeding and uterine contraction status; for now, check weekly, and once stable, change to every two to three weeks.
What precautions should be taken? Is sexual intercourse allowed? To avoid uterine contractions, sexual intercourse is not advisable.
What foods can help eliminate blood clots (is it okay to take Chinese medicine)? Avoid raw, cold, and easily fermented foods; for issues regarding Chinese medicine, please consult a traditional Chinese medicine practitioner.
Sincerely, Lu Li-Zheng.

More Info


Bleeding during pregnancy can be a concerning symptom, and understanding its causes, risks, and appropriate care is crucial for the health of both the mother and the fetus. In your case, experiencing significant bleeding at 11 weeks of gestation, along with the presence of blood clots, raises several important points to consider.


Causes of Bleeding and Blood Clots
1. Implantation Bleeding: Early in pregnancy, some women experience light spotting when the embryo implants into the uterine lining. However, this typically occurs around the time of the expected menstrual period and is usually not heavy.

2. Subchorionic Hemorrhage: This is a common cause of bleeding in early pregnancy, where blood collects between the uterine wall and the chorion (the outer fetal membrane). It can lead to blood clots, which may be absorbed by the body or expelled.

3. Miscarriage: Unfortunately, bleeding can also indicate a miscarriage, especially if accompanied by cramping or passing tissue. Given your history of two previous miscarriages, this is a significant concern.

4. Ectopic Pregnancy: Although less common, an ectopic pregnancy (where the embryo implants outside the uterus) can cause bleeding and is a medical emergency.

5. Cervical Changes: The cervix can become more sensitive and prone to bleeding during pregnancy, especially after intercourse or a pelvic exam.


Risks to the Fetus
The presence of blood clots does not automatically mean that the fetus is at risk. In many cases, the body can absorb the blood clots without affecting the pregnancy. However, if the bleeding is heavy or persistent, it could indicate a risk of miscarriage or other complications. Regular monitoring through ultrasounds and blood tests can help assess the health of the pregnancy.


Monitoring and Follow-Up
Given your situation, it is advisable to have regular follow-ups with your healthcare provider. The frequency of these visits can depend on the severity of the bleeding and the size of the blood clots. Typically, if bleeding is significant, your doctor may recommend ultrasounds every week or every two weeks until the situation stabilizes.

When to Seek Immediate Care
You should seek immediate medical attention if you experience:
- Heavy bleeding (soaking through a pad in an hour)
- Severe abdominal pain or cramping
- Passing large clots or tissue
- Dizziness or fainting

Sexual Activity and Diet
Regarding sexual activity, it is generally recommended to avoid intercourse during periods of bleeding until cleared by your healthcare provider. This is to minimize the risk of further irritation or complications.

As for diet, while there is no specific food that can "remove" blood clots, maintaining a balanced diet rich in vitamins and minerals is essential. Foods high in vitamin K (like leafy greens) can support blood health, while staying hydrated is crucial. If considering herbal remedies or traditional Chinese medicine, consult your healthcare provider first, as some herbs may not be safe during pregnancy.


Conclusion
In summary, while bleeding and the presence of blood clots during early pregnancy can be alarming, many women experience this without serious complications. Regular monitoring and open communication with your healthcare provider are key to managing your pregnancy healthily. Always prioritize your health and well-being, and do not hesitate to seek medical advice whenever you have concerns.
