Sub chorionic hematoma

Aimee
Anyone else have a hematoma while pregnant?  I thought for sure I miscarried yesterday I felt a little rush so I went to the bathroom and all hell broke loose.  Blood everywhere floor me toilet bathtub everywhere!  Went to the ER and baby is fine but I have a subchorionic hematoma which could or could not lead to a miscarriage. Anyone any experience?
