When is your follow up appointment to discuss the scan results?

Until you have had this consultation please try to put the brakes on any speculative thoughts.

Remember sonography is a complex skill, and not something you can pick up on Google.

As for the sonographers expression, it's not wise to read too much into this, the man
who did my 20 week scan had a deeply serious unsmiling expression throughout. My mind did anxious somersaults but it was just his manner, everything was fine.

Take care and practice any relaxation strategies you have while waiting for results, and stay away from Google.
