Psychological changes in pregnancy are not as easily measurable as physical changes. Pregnancy involves psychological changes that result from adaptation to corporal, emotional and social changes, often the result of intrapsific reorganization inherent in the new condition of future mother (Blum, 1980). These changes arise from the need for assumption of the new role as a mother and also of the processes linked to cultural and learning factors, aspects these that tend to interfere with pregnant women (Rim and Vieira, 1988).

Maternity is not always synonymous with emotional maturity, although it is the most important experience of woman's psychosexual development. Waiting for a child, especially if it is for the first time, involves feelings and psychological changes that are a challenge for the pregnant (Colman and Colman, 1994, grass, 2000). Stool and Vieira (1988) refers to pregnancy as a development crisis, corresponding to a situation of change at biological, psychological and social level, which requires women an additional effort to maintain psychological balance. If the pregnant woman comes from the crisis situation in a favorable way, she will also come out with the enriched personality, acquiring psychological immunity, since the woman learned to deal with the situation, issuing a behavior that was properly reinforced (Silva, 2008).

According to Larger (1983), the desire to have a child may arise from the woman's desire to prove her own fertility; For this desire for fertility they can influence more conscious and rational aspects, such as being able to revive their own childhood, or the desire to provide their child with a child other than the one who had or would have had. The need to achieve a certain statute can also take a woman wish to have a child. However, in reality, according to this author, the desire to be a mother comes from the psychological need of the woman to demonstrate her latent abilities. CANAVARRO (2001) defends another idea, in which it poses that motherhood arises as a need for personal fulfillment.

Lamb (1986) considers that one of the reasons for the decision to be a mother is to realize ideals and lost opportunities. The imagined son closes the ideal of the ego of the parents, the desire to renew old relations, constituting an object of transfer of feelings and unconscious relations of the parents and, the double opportunity of the separation and replacement of the mother itself. The relationship with his own mother during pregnancy is intense, and can be enhancer of internal conflicts, generating simultaneously, feelings of guilt. This author also points out that there are two perspectives to psychologically frame pregnancy: (1) pregnancy as a development phase, in which pregnancy plays a significant role in the woman's personality preparing it for maternal care, completing maturation in the psychological and physiological Pregnancy introduces new living conditions and constitutes a crisis, which is not pathological, constitutes a turning and adaptation to a new status: the mother; and (2) pregnancy as an obstacle to win, in which pregnancy corresponds to a kind of disease, being included in the so-called "mechanical diseases", presenting transitional changes that lead to disorganizations and pathological reactions in fraga Adaptation to the pregnant paper is difficult, especially when it comes to a first pregnancy of women. According to Gomes Pedro (1985) a first pregnancy, is an authentic challenge to the adaptation of women as a person "(...) in their cosmic balance where their anxieties are projected, their defenses and their dreams." 


The pregnant woman is a theme of social interest. KITZINGER (1984) states that the woman in pregnant loses her intimacy, being the subject of interest and concern for society. Mendonça (1998), Citing Maldonado (1976), states that pregnancy as a developmental crisis presents some particularities, and the woman loses her uniqueness, a symbiotic and dual relationship with the fetus, requires adaptations and adjustments During pregnancy, natural phenomena occur that involve complex psychological states, since from Statem to the end of pregnancy, the psychological assignments with which the pregnant is here are diverse, and the fears, According to Blum (1980), the answers to these tasks are influenced by several factors, such as the state of health, the matrimonial state, age, relationship with peer, the psychological development stage, intrapsychic and conflating needs.

From the moment the pregnant woman takes knowledge and awareness of her situation, she becomes necessary to acquire new patterns of behavior, there is a redefinition of roles and a need for adaptation to these new roles, the need for redefinition of roles, emerging.
