After pregnancy, one of the favorite topics for mothers to communicate with is [is your due date in what]?
Many pregnant mothers even plan their daily itinerary accurately as the [expected date of delivery] approaches.
But is it necessary to do so? Clove’s mother invited chief physician Duan Tao to tell us about the expected date of delivery.
In fact, for women, there is no need to struggle too much when calculating and waiting for the expected date of delivery.
This is not much different from waiting for menstruation every month when you are not pregnant, and it is also a bit similar to waiting for your boyfriend when you are dating at ordinary times (except that premarital dates are basically when you arrive late, and after marriage, you will get out of control and your husband will arrive late): basically, you arrive around the appointed point, and there are still few who are really on time.
The same is true of the expected date of delivery. Only about 5% of pregnant women actually give birth on the expected date of delivery.
There are many ways to calculate the expected date of delivery, the most commonly used now is the method proposed by Dr. Naegele of Germany in the early 19th century.
The principle used in this calculation method is to assume that the menstrual cycle is 28 days and the duration of the whole pregnancy is 280 days (40 weeks).
According to this calculation method, there may be such a distribution:
About 5% of women give birth on the 40-week expected date.
About 25% gave birth 3 days before and after the expected date of delivery;
About 50 ~ 60% delivered within one week before and after the expected date of delivery.
About 80% gave birth within 2 weeks before and after the expected date of delivery;
Another 20% gave birth before 38 weeks and after 42 weeks.
According to the current calculation method, the expected date of delivery is a point. In fact, in the view of obstetricians, the expected date of delivery should be a face.
As long as the child is normal, delivery on any day between 37 and 42 weeks is normal.
Because the expected date of delivery is calculated according to the [standard person] with a menstrual cycle of 28 days, without considering differences in age, delivery, menstrual cycle, race, etc.
Even if all the considerations are taken into account, the time of delivery will still be different, so there is no need to struggle if the expected date of delivery has not yet arrived.
What should I do if I haven’t given birth by the expected date of delivery?
Listen to the doctor and do whatever you have to do.
Attention should be paid to carefully counting fetal movements every day, and fetal heart monitoring and ultrasound examination should be done when necessary. If you have nothing to do, you will have a baby when you walk.
What if you don’t give birth in 41 weeks?
Normally, the doctor will help you make a judgment.
If the conditions for natural labor are met, most of them will require you to be hospitalized and prepared to help you give birth. If the cervical conditions are not good, use drugs or other methods to promote cervical ripening, and if the cervical conditions are good, you will be prepared to induce labor.
In general, we do not want to delay until after 42 weeks of pregnancy, because the risk of adverse perinatal outcomes will increase after 42 weeks.
Having children is like bearing fruit on a tree. When it is ripe, it will fall off. It doesn’t matter when it will fall off. What if it doesn’t fall off after it is ripe for a long time? Go get it.
Having children is not mathematics, it will not be so accurate, and there is no need to be so accurate.
