Placental blood clot at 16 weeks of pregnancy?
Hello, Doctor.
I had a smooth first pregnancy, and during my business trip to France at 4-5 months, I had no issues carrying luggage.
This is my second pregnancy.
During my 12-week check-up, the doctor mentioned that my placenta was low and advised me to be cautious.
At 16 weeks, after doing housework for two hours, I suddenly experienced heavy bleeding at night.
We rushed to the hospital in the morning for a progesterone injection.
The doctor informed us that there was a blood clot in the placenta measuring about 7 cm, and we could only wait for it to be absorbed naturally.
During this time, I have been on bed rest, but it has been two weeks, and I still occasionally pass brown or dark brown blood.
I would like to ask the doctor if this is normal.
Is the dark brown blood I am passing part of the placental blood clot? My obstetrician mentioned that the blood clot would only be absorbed and not expelled, so I am quite worried.
Thank you.

If the blood is just dark brown, it indicates old blood rather than fresh blood, which is generally not a concern.
Some blood clots may be absorbed, while others may break down and be expelled.
Sincerely, Dr.

More Info
Understanding placental blood clots during pregnancy, especially at 16 weeks, can be a source of concern for many expectant mothers. In your case, it seems that you experienced a significant amount of bleeding, which understandably raises alarms. Let's break down the situation based on your description and general medical knowledge.
Firstly, it's important to note that the presence of blood clots in the placenta, particularly at 16 weeks, can occur for various reasons. The placenta is a vital organ that develops during pregnancy, providing oxygen and nutrients to the growing fetus while also removing waste products. When there is bleeding, it can lead to the formation of blood clots within the placenta. These clots can vary in size and may be a result of placental abruption (where the placenta detaches from the uterine wall), or they may simply be due to localized bleeding within the placenta itself.
In your situation, the fact that you have been advised to rest and have received medication to support the pregnancy (often referred to as "tocolytics") is a standard approach when there is bleeding in early pregnancy. The bleeding you experienced, particularly if it was sudden and significant, can be alarming, but it does not always indicate a severe problem. The color of the blood can also provide clues; fresh red blood often indicates active bleeding, while brown or dark brown blood typically signifies older blood that is being expelled from the body, which may be less concerning.
Regarding your question about the brown or dark brown discharge you are experiencing now, it is likely that this is old blood that is being expelled as your body absorbs the blood clot. While your doctor mentioned that the blood clot would likely be absorbed rather than expelled, it is not uncommon for some of the older blood to be released as the clot resolves. This process can take time, and the duration can vary from person to person.
It is crucial to monitor your symptoms closely. If you notice an increase in bleeding, the return of bright red blood, or any new symptoms such as severe abdominal pain or cramping, you should seek medical attention immediately. Regular follow-ups with your healthcare provider are essential to ensure that both you and your baby are doing well.
In summary, while the presence of a blood clot in the placenta at 16 weeks can be concerning, the fact that you are experiencing brown discharge may indicate that your body is processing the clot. Continue to follow your doctor's advice, maintain a restful lifestyle, and keep an open line of communication with your healthcare provider. They are best equipped to monitor your condition and provide guidance tailored to your specific situation. Remember, every pregnancy is unique, and staying informed and proactive about your health is key to a successful outcome.
