I was diagnosed with a 2 .6*0.4cm subchorionic hematoma at 13 weeks during my first pregnancy.there has been no spotting or bleeding thought. I did another scan at 24 weeks at a different medical center the radiologist said everything was OK. Could he have missed seening it and its still though he said its gone .am concerned because the ultrasound graphic is not very clear. Could he have missed it as a result????
