By looking it up it also means a sub chorionic heamotoma. I have had this with my last 3 pgcys. The last pgcy had the SCH pressing up against the sac which made the sac out of shape, once the bleed had dissolved, our passed through the sac went back to its normal correct shape. I am expecting something similar with this pgcy since the last 3 had one. I guess will find out next week. With the last pgcy they had mentioned that once the bub is bigger than the bleed it should be fine.
