I am currently 13 weeks PG, I had an U/S a few days ago but got called back for another as there were concerns with the first one. The OB has told me that the baby's brain development is at the lower end of normal for development. I did not have a CVS as he was pretty confident it wasn't down syndrome, I came back as 1 in 3000, but I will have to go in for another U/S in three weeks, and a possible amnio. Has anyone else out been told something similar? What was the outcome? Even though the OB is pretty sure that everything will sort itself out, as everyone is a little different with their development, as you can imagine I'm feeling pretty nervous!
