Water on the brain *worried*

Shannon

I just left my doctors office after a general check up and am 29 wks 4 days . My doctor told me the baby had a little extra fluid on the brain and that he would schedule me for a sono at the hospital with a high risk doctor. The baby is measuring 31 weeks and weights 3lbs 10ounces.

All previous testing came back great, did genetic testing aswell no issues. Anyone have any thoughts or experience with this?

Thanks in advance
