Because they weren’t anticipating any issues neither of those ladies had their companion with them, although both had taken a good friend or relative as a substitute and were glad to not be alone. One of them explained how she knew right away from the behaviour of the person doing the scan (the sonographer) that something was mistaken, despite the precise fact that she was supportive and tried not to make her anxious.
