I also had a subchorionic hematoma this pregnancy. I hemmorhaged 4 times with bright red blood before I was put on bed rest. I never had another hemmorhage, but I did have brown bleeding for several weeks that ended right before I started my second trimester. The clot was at the edge of my placenta, and it eventually moved out from under the placenta and started to shrink. By 18 weeks, it had been reabsorbed by my body. I'm also 34 weeks and doing great. My doctors always told me that 9/10 pregnancies with sch progress with no issues, so don't give up hope! However, you should really go see an OB and take the records from your ER visit. Prenatal care is a necessity, especially with any complications like a sch. The doctors will most likely want to do regular ultrasounds to make sure the clot is not impeding the baby's growth, which is one of the biggest risks associated with this (in addition to placental abruption).
