Long bones measuring small

Stephanie
Hi - we had a growth scan on Monday which showed our babies long bones ( arms and legs) are a few weeks behind while the rest of her is normal. Today, Friday, we saw a specialist that said she's 80% sure our baby has dwarfism. At all our other scans our baby measured normal so this came as a complete shock to us. Ive read so many different stories online from good to terrible. Just wondering if anyone else has had this experience? If so, what was your outcome? Any advice or guidance would be greatly appreciated!! Thanks!
