Detailed Answer:
Hello
Thanks for writing to us with your health concern.
Can you please upload the exact
ultrasound scan report for a better opinion ?
From the information provided, there is minimal sub chorionic bleed in the sac of Twin B.
The chorionic tissue supports the baby, in future, it forms the placenta.
There has been some amount of bleeding in this tissue, this increases your chances of miscarrying the twin B.
However, not all such sub chorionic bleeds will necessarily lead to an
abortion.
Sometimes, the blood gets absorbed, and bleeding stops, and the
pregnancy grows normally.
Only if the bleeding continues and increases is there a cause for concern.
Right now, what you can do is - take rest.
Avoid
stress, intercourse and jerky travelling or standing for
prolonged periods.
Take the medications as prescribed - Susten (
progesterone ) for support to the embryo and
aspirin to increase the blood flow to the baby.
A repeat scan done after one week will tell you if the situation has improved.
As you have not had any spotting or bleeding, it is a good sign
Since the collection is sub chorionic ( behind the chorion ), the blood just gets collected and sometimes there is no visible vaginal bleeding / spotting.
So please do not worry.
Right now , just take rest, and think positive.
Repeat the scan after a week.
In case of bleeding / spotting / bad cramps - visit your doctor immediately.
All the best
