13w ultrasound today. Sad.

Sa
Everything looked normal, the heart, legs, arms, brain, but the doctor said the fluid behind the neck was abnormally thick. This indicates a likelihood of disability. She said in all likelihood it will be ok but need to decide if we want an amniotic needle test done which can cause miscarriage. She also recommended another test at 16 weeks before we decide whether to do the needle test. 
Can anyone here share a similar experience and that their baby was fine? 
UPDATE
hi ladies, had the 16w scan and everything was normal. Thanks for the help and advice. Was so relieved!!!
