I think many women have premonitions of these things. A while back, I was on an infertility discussion list. One of the women on the list posted something one day about how she had a dream the previous night about having twin daughters, and one of them was moving away from her. She had her last IVF the next day, and two weeks later she posted that she was pregnant. A few weeks after that, she found out it was twins. Another few weeks later, she lost one of the babies. The one that made it full-term was a girl.
