I was diagnosed with a subchorionic haematoma at 14 weeks after bleeding from 12 weeks (heavy bleeding with clots for 1 day followed by brown bleeding, with one more day of red bleeding at 13 weeks, followed by brown bleeding till 16 weeks + 2). The clot measured 15x11x27 mm. I got told to take it easy but not bed rest and return to be rescanned in a couple of weeks. I went back today (17+3 weeks) and the hematoma has got bigger and is now 22.2x28.2x18 mm. It is adjacent to the placenta. The sonographer was really uncommunicative and the MW very uncertain. Does anyone know if this a small, medium or large clot? Or anything about subchorionic haematomas at all? Most of the stuff on the internet is to do with 1st trimester haematomas. Any advice/experience would be much appreciated.
