Subchronic heamotoma

Hi ladies,
At 6 weeks I started bleeding and heavily. And rushed to the EPU who confirmed a subchronic heamotoma. I went back for a scan last week 9 weeks and heamotoma is very large. I have now started losing dark brown blood and been told that it's bleeding out. I was also told that my body might absorb this. I just want to know my chances and how long it normally takes to resolve
