SCH (Subchronic Hematoma)

I'm curious if anybody else has experienced a SCH? I first had a bad scare when I was around 5 weeks. Pouring the blood and hurting bad. I went to the ER. HCG count was fine. Baby was fine. I bled maybe 3 or 4 times after that (bright red). My SCH is 8cm big. Now I'm 11 weeks 4 days and  haven't bled in 5 weeks. I woke up this morning to light brown blood. Anybody else experience this?
