Ultrasound at 19 wk showed more fluid in brain

Has anyone been told that one of their baby has more fluid then normal in their brain? That’s what happened to me yesterday. Just hearing that devastated my husband and I. Anyone out there experienced the same and their child came out fine? Please help me make me feel better. I’m hoping the doc is wrong. I have to go for a MRI soon and see a nero specialist in the up coming weeks. I’m trying to stay positive. HELP 😩😢😓
