Method: A qualitative content analysis with an inductive approach has been used to analyze fourteen interviews that served as the data base for this study. The content analysis resulted in the development of five categories which evolved into one primary theme. Findings: The five categories identified were Worry and preoccupation;Distance;managing their feelings;Mourning what is lost;Guarded happiness and expectations. These categories were compiled into a main theme, “Worry consumes a lot of energy, but on the other side lies happiness”. This theme focused on whether the women could feel any happiness about being pregnant again despite their concerns with the previous miscarriage. Conclusions: The emotional states of the women when they get pregnant again are typically characterized by anxiety, worry and concerns about their current pregnancy. The women have a tendency to distance themselves emotionally from their pregnancy but also strive to find the joy of being pregnant again. During the new pregnancy they find themselves in need of support from their family and friends as well as in need of support from the healthcare system.展开更多
