Need Subchorionic hematoma info

Okay so I was told that I have SCH and I want to know if anyone on here could tell me their with this. And please not spare me any details. I know that probably sounds weird but I am a very worrisome person. Like what color the blood was and how long the bleeding lasted and how much it was bleeding. I just want to make sure I'm not bleeding too much compared to other people.

The baby is measuring to be 6 weeks 2 days. They didn't find a heartbeat but I know they might not at 6 weeks.

I had some brown spotting that turned dark red last night. And then started again with dark red/brown around 3:30 pm. Please just help me understand. I've had a miscarriage before and I'm trying to worry.
