Zugaib and Sancovsk (1994), affirm that prenatal consultation if coats with an importance redoubled in relation to any another one, therefore from it orientaes for possible medicine administrations result disgnostic and prescribed by the doctor or not, that they will influence of considerable form on the development of two customers: the gestante and the product of the conception. For Branden (2000) the accompaniment of the prenatal one must be carried through during all the gestation until the after-childbirth. The agendamento of the consultations for prenatal a normal one if extends each four weeks, until 28 week of gestation; one consults to each two weeks and, after that, weekly until the childbirth.
