Hemorrhage around placenta

So I'm right at 6 weeks and started having some strong back pains accompanied by some bleeding went to the E.R.and they said I had a hemorrhage right next to my placenta that could possibly cause it to detach and I could miscarry and there is a chance it might heal itself they were not clear but it's extremely painful my little tiny baby has a heartbeat and seems to be ok but if the placenta detaches it will not matter it's painful and I'm stressing my self to the point of depression I'm so scared has anyone heard of this before I could really use some positive information or really any at all calling the doctor in the morning.
