Subchrionic Hematoma

Is this a big one or a small one? When I went to the hospital they didn’t bring it up at all so I wasn’t even aware I had one until I checked my medical records from that day, the doctor didn’t put me on any type of restriction or gave me anything for it and I haven’t had any bleeding except the little bit I had on that day and everything else was fine and so was the baby but I can’t help but worry.
