How to know when the delivery will be?

They just confirmed it: you are pregnant! Now it only remains to know when you are going to give birth. But how do you know when your birth will be? The expected due date (FPP) is set according to the last menstrual period, but depending on whether the woman’s menstrual cycle is regular or irregular this may vary.

Therefore, it is also important to keep in mind that it is really a date estimated by gynecologists, but that it has no value at all, but that it is simply an approximate estimate so you can at least know the week or fortnight of the year in which you will give birth.

However, and as in theory it is practically impossible to know exactly when the baby will be born in practice three methods are used basically to know the estimated date. Which are?

  • Calculate by weeks (not all months have the same duration). Add 28 weeks to the date of your last period (FUR) or 266 days.
  • Count nine months from the date of conception.
  • Add seven days to the date of your last period (FUR) and subtract three months.

What is the most frequent week in which labor usually occurs?

About 4% of babies are born on the estimated date of birth, that is, a very low percentage, what about the other babies?

The rest of the newborn babies that arrive in the world do so, either before the 40th or last week. 70%, in fact, is born in the ten days near this date, and 90% do so between week 38 and week 42.

Pregnancy is not an exact science. From week 37 a baby that is born would actually be a baby born at term, although it is normal to be born around 40 or 41 weeks gestation.

It is also considered normal, however, for a baby to be born at week 42, that is, up to five weeks apart. But what can cause a baby to be born before or after week 37? The size, placement of this, the state of the placenta, the mother’s daily activity or whether the mother is first or not.

According to some studies, about 70% of new mothers give birth last week 40.

Does it seem that childbirth will never come?

When a pregnant woman passes the week 40 and does not notice that there are already some indications that labor is approaching, it is normal for stress and, above all, nerves, to begin to appear.

However, it is important to know that it is commonplace, that is, there are many that last longer than expected. It is not possible to consider, of course, a late pregnancy to any pregnancy that passes from week 40, but to that which passes from week 42. In fact, the percentage that exists of late pregnancies is actually about 5%.

Late pregnancies usually occur for reasons such as an error in the date of calculation, remember that doctors estimate that the date of conception occurs fourteen days after the last menstruation (date of delivery).

However, very few women have a regular cycle of 28 days. Another reason is due to a physiological delay, that is, that the egg after fertilization takes longer than expected to nest in the mucosa of the uterus or that the fetus has matured more slowly than normal.

It can also be caused by hormonal changes, since sometimes hormones undergo some variations, especially if pregnancy occurs after forty years; for the consumption of medications, because taking certain drugs such as analgesics near the date of delivery could also delay the onset of contractions; and, finally, for being a first-time mother.

According to some experts, in fact, primiparous women are more likely to have their first child last week 40 so that the cervix is ​​prepared to give birth.
