Subchorionic Hematoma

Can you tell me what your experience with SCH is?
Pardon the language I'm about to use but it makes my point....I had red blood when I wiped last night, and freaked THE FUCK out. I would call it heavy spotting.
 Went in for another scan this morning, the spotting has turned brown, and Bean's heartbeat is still a strong 144.
Given my miscarriage in March, I was hoping to just have a normal, blood free pregnancy!
