A peri-sac hematoma like this is common in early pregnancy and usually settles on its own over 1 to 3 weeks, especially with a single live pregnancy and a heartbeat already visible on your scan. Complete rest, avoiding heavy lifting and strenuous activity generally helps it resolve.
Next Steps
Your doctor has already stopped Ecosprin because of your raised protein C, so keep following that plan rather than restarting it yourself. A repeat scan in 1 to 2 weeks will show whether the hematoma is reducing, and the ovarian cyst and fibroid your scan picked up are usually just watched alongside your pregnancy.
Health Tips
Go in sooner if the bleeding gets heavier than spotting, you pass clots, or you get cramping or pain. Please discuss this with your obstetrician closely, given your clotting history.
