I had laparoscopic myomectomy, I have now been diagnosed with a large 10cm pelvic hematoma?

I had laparoscopic myomectomy five months ago for a large subserosal fibroid- surgery went well with no complications. Three days ago I had abdominal pain and after going to the ER, I’ve been diagnosed with a large 10cm pelvic hematoma. After being monitored for 24 hours with regular bloods, temperature, blood pressure and ultrasound I was considered stable and able to leave hospital. I return tomorrow for further ultrasound and bloods to see if it’s still the same. I am not in my home country and do not have access to my surgeons. What is the best course of action for a stable but large hematoma? I’m now just in mild pain, resting with a heatpack and panadol, and no fever or nausea.
