Yes one gestation usually ends around 38 to 42 weeks. After 42 weeks, gestation is considered prolonged and, in most cases, is induced for the term.
The woman who gives birth between the 38th and 42nd weeks of gestation will have one newborn to full term, that is, within the period considered healthy for birth. Before the 38th week, the baby will be considered pre-mature and after the 42nd week, it will be considered to be post-term.
That is, if you are with 40 weeks and the baby was not born, that is completely normal. You must continue prenatal care routinely for evaluations of your health and fetal health.
Each baby has an individual period of training and maturity. This time must be respected and reflected in labor that will culminate in birth.
