Subchorionic Hematoma....?

When I was 18 weeks at 4am I went to the ER due to a gush of heavy bleeding. They ran tests and ultrasounds and said it’s a subchorionic hematoma (I was told was normal, didn’t have it in my other 2 pregnancys)

Fast forward to day, I’m 26 weeks and 4 days and I noticed a few dropped of blood in my underwear (nothing when I wiped). I called the nurses line to my OB she said that’s ok and normal only serious if it was like a period and filling a pad.

Just curious as to know if any others mamas are going through this or have ever went through this?
