Sonographers are highly trained at performing u/s. This obviously requires a vast skill and knowledge. She is at the front line - anything looking a bit iffy she would call in the radiologist or in this case the fetal medicine specialist to look. However, all u/s work is saved in real time and the specialist will review with alerts to anything that the sonographer may be concerned with.

As for personalities - that is just the way life is. Some are personable - happy and receptive. Others not so much so. I might add, when I was pregnant with Immy my fetal medicine obs had a sonographer working for him that I found very "droll". She looked like she wouldn't smile if she won the lotto. She also worked at the RWBH and I found her doing my daily u/s - she was just incredible. Awesome. It taught me that we just never know. She came to my room after Im was born just to congratulate me.

I know it's hard when you are so excited and happy -

Sonographers can only give you a risk ratio if the medical officer directs this. This would only be done if all was fine. Just like a nurse. We can give out test results under the direction of a medical officer (unless I was a nurse practitioner that is different again).
