Read my ultrasound report from 8 weeks after they posted it on my medical portal. I had already had my appt with the doctor and we heard the heart beat at 180. But the notes stated that there was chorionic debris and a 4 mm cyst on the umbilical cord. Well 30 minutes into the mayo clinic boards and a comment about a 23% correlation to DS and I was convinced my baby had DS... Then came the statistic research for " advanced maternal age".,, and the tears came quickly.
