The ultrasound looks fine NT of both the twins is fine
Thrre is a single placenta mentioned in the scan, however the septa between the babies may mean that they are in separate amniotic sacs
However the information is incomplete
You need to provide me with your early pregnancy scan
The placenta is low lying and covering the os
This may eventually change and move up as the pregnancy grows, so do not worry about it right now
Next Steps
No intercourse as your placenta is low lying
Avoid lifting heavy weight
