Does Subchorionic Hemorrhage Spotting Come and Go??

Hi all! So I have a small SCH (Subchorionic hemorrhage) but didn't have any spotting the past few days. I figured it was over but this morning I had a little more brown spotting here and there. Is this how SCH works? Of course I'm nervous as heck since I had thought it was over and wasn't expecting any more 😁Please any help or thoughts would be much appreciated. Oh and I am 12 w 1 day today, have my next u/s appt Monday.
