Subchorionic hemorrhage

Has anybody dealt with, or know someone that has, a Subchorionic hemmorage? I was diagnosed with it at 8 weeks. At 12 weeks they noticed that the blood pocket had caused a tear in the placenta. I was terrified. Still am. I am now 16 weeks and was told that it looks like it has healed, but I'm still so worried I'm going to lose the baby.
