Among all the changes that the family system faces throughout the life cycle, the transition to motherhood is highlighted as one of the most dramatic and intense (Ngai & Ngu, 2013). Society still romanticizes motherhood and expects women to feel happy and fulfilled when becoming a mother, but it is a moment with many adaptations and challenges, which can even be sickening. The objective of this work was to understand the transformations in subjectivity, in conjugality and in the career that the woman experiences when becoming a mother in contemporary times. The qualitative study interviewed 20 women between 25 and 40 years old, primiparous, with babies between 4 months and 2 years old, in a stable relationship and who have paid work. It was found difficulty in recognizing oneself after motherhood, overload with accumulation of functions, challenges to reconcile career, decline in intimacy and sexual life with the partner, importance of the support network, in addition to self-demand and feelings of inadequacy due to excess of information on the internet and comparison on social networks. Currently, there are several studies with excerpts from these themes - motherhood, conjugality and career, but few that propose to correlate these different factors. Therefore, it is believed that the results of the study can contribute significantly to the understanding of relevant themes to the promotion of women s health and well-being in contemporary times.
