The intentional sample was made up of five adolescents aged between 16 and 19. The study was carried between June/2008 to October/2009. Semi-directed interviews based on the trigger question “Tell me about your pregnancy and your baby's birth”. The data were submitted for thematic analysis and from this the following categories emerged: 1. Late discovery of pregnancy: “Mine was a lightning pregnancy”; 2. The symbolization of the child: “It was a present for me…” discussed within a theoretical framework of reference, with special emphasis on the psychodynamic approach.

On a psychological perspective, the adolescents had presented feelings of omnipotence, unfamiliarity, shock, surprise, anger, fear, anguish and happiness at the birth of their child. They appeared to use immature, narcissistic and neurotic defence mechanisms such as denial, dissociation, acting out and idealization as well as revealing the desire to be good mothers and to engage in maternity.
