The study intends to develop a predictive model of spontaneous onset of labor between 39 and 41 weeks of pregnancy in women carrying singletons and without indication of delivery before this date. The main hypothesis is that a combination of clinical, ultrasonographic, biochemical and/or biophysical variables will allow to differentiate women who will spontaneously trigger their labors from those who will require an induction by the term of their pregnancies. A tool of this kind should aid in the individualization of the management of the final weeks of pregnancy and, at the light of recent evidence, provide support to the decision-making processes.
