Subchronic Hematoma??

Went to the ER yesterday cause I woke up to bright red blood between my thighs and when I peed. they diagnosed me with a subchronic Hematoma & told me that the baby is okay for now.. has anyone had experience with this before?

I’m 9 weeks pregnant today, and have had occasional spotting (2-3 times) since I’ve found out at week 5. The spotting has normally been really light & more brown than anything though.

This is my first pregnancy and I’m extremely worried that I will have a miscarriage.
