Help....

So someone very very close to me just went to her 35 week scan and they found fluid on the baby's left ventricle of the brain that has not been there in previous scans. She is being referred to a specialist but I'm just wondering if anyone else has experienced this and can give some insight on what it is and what it could cause in the future. I just want this sweet baby to be ok. She has had multiple miscarriages and this baby is such a gift. I know she is terrified and hurting right now. I'm just curious about what it could be/mean? Thank you!
