Fluid around baby

We got the devastating news that our baby has what looks like a fluid sac around it at the abnormality check. They also advised they can see a couple of other signs of defects. We are in bits and after a lengthy conversation with the specialist our heads are sore and no idea what to think. We go back next week for another scan check up and to decide if I want the actual invasive test. He doesnt think we even have the 15% of things being normal :(. This was our (natural) second pregnancy after having our ivf baby.

Has anyone been through this and what was the outcome? Please share your experience as I really need advise.

Thank you x
