Apart from Joseph, the news from the shepherds was the first confirmation from the outside world, that the her baby was the awaited Christ.

This news, would have bought joy but then she also knew that from then on, she had to share him with the world.

There would have been two areas of concern.

1) Spiritually she would have been uplifted by the source of her pregnancy but stressed of her rejection in her normal  social position.

2) Physically she would have been stressed and uncertain how she would cope with the dangers to her unborn child.
