Subchorionic hemorrhage experience?

I started bleeding on 8/10/20. It was very light pink that night, brown by the next morning, and then turned bright red and was a flow. I went to the ER and they did an ultrasound, showing the baby was ok, had a heartbeat and that I had a SCH. Since then, for the past 5 days I have had heavy red bleeding with clots ranging from small dots, to over a quarter in size. I’m also experiencing moderate cramping. I got a follow up ultrasound yesterday (8/14) that showed the baby is growing and heartbeat is strong. Also they said the hemorrhage has reduced in size. It’s so alarming bleeding this much. Does anyone have experience with this? How long does the bleeding last? I also have slow rising hcg and don’t know if that’s a concern now that the baby has a heartbeat. Any info is appreciated! Thank you!
