Why don't fortune tellers get pregnant?

Why don't fortune tellers tell fortune if they don't count pregnant women as pregnant? Ying Hui's colleague is about to give birth, which is a happy event. However, unexpectedly, the child left a few days before the due date. This is really lightning! According to the hospital, this is because the umbilical cord of the child is intertwined, which means that the umbilical cord is entangled in a mess, which affects the child's breathing and nutrition, and finally disappears a few days before delivery. Ying Hui is very sad. She said that the baby's fetus has little activity. She thought it was a child who didn't like to talk, so she didn't move much, but she didn't expect this to be the child's distress signal!
