What if the child is late? Over-term pregnancy

If at 40 weeks nothing happens yet, there is no need to be alarmed: pregnancy has a duration ranging from 38 finished weeks to 42 finished weeks, so the time frame in which it is possible for the baby to be born is very large. In fact, only a small percentage of women give birth on the day the gynecologist indicates how "presumed date of delivery", while most give birth to their baby spontaneously within the forty-first week.



It is not yet clear what triggers the mechanism that initiates labor, although it is hypothesized that several factors act in synergy to make this happen. Among them, the aging of the placenta; the decrease in amniotic fluid; the increase in the blood of oxytocin (hormone that promotes contractions) and estrogen, which occurs right at the end of the pregnancy. Pregnancy is considered over-term or, more correctly, "protracted", if it exceeds 42 weeks (294 days calculated from the date of your last menstruation). Protracted pregnancy affects 5-10 percent of women expecting a baby. In Del Paese, when the pregnancy lasts beyond 41 weeks + three or four days, doctors intervene to induce birth through the use of prostaglandins and oxytocin. The duration of pregnancy is influenced by familiarity and has a certain relationship with the duration of the monthly cycle (interval between one menstruation and the next): women who, before becoming pregnant, had cycles of more than 30 days tend to be later than the expected date of delivery more than future mothers who, before pregnancy, had close menses.

At this point it is ready, indeed very ready to be born and from now on, every moment is really good for the onset of labor. The small organs are in fact fully formed and a greenish substance called meconium, which is the amniotic fluid that the baby swallowed during gestation. This meconium will be expelled with the first stool.

At the end of this last week it weighs on average 3200-3400 grams and is about 50-52 centimeters long.
