They say not to worry but how can I not 😔

Hi everyone my name is Daisy I’m expecting my first baby in feb I just had my 20 week appointment and we there was some bad news they say they found some liquid around the baby’s heart and they are sending us to a specialist to rule out anything just to Make sure what’s going on has anyone ever had anything similar to this ? They says it’s not in her longs or anywhere else she’s growing at what she’s supposed to and a strong heart beat can anyone help? I haven’t stopped crying about it I sido the wrongs thing and try to look for it but not much is out there
