How can there be ten months of pregnancy when there are clearly only 280 days?

Data shows that the vast majority of children are born within 2 weeks before or after their due date; only 5% are born on the day of their due date; and 25% are born 3 days before or after their due date. In life, some pregnant mothers have a misunderstanding of "10-month pregnancy", they think that "10-month pregnancy" is a calendar full of ten months, but this is not the same as what the medical science says. The difference between this and the medical term "10 months of pregnancy" is obvious.

Some mothers have even been known to make a lot of woo-hoo out of this misunderstanding, such as giving birth to a baby, only to learn the truth about "10 months of pregnancy".

Pregnant mothers who are about to give birth are still thinking about the ten natural months

There was one pregnant woman who was in contact with this woman. She was pregnant for the first time and didn't realize until the moment she was pushed into the delivery room that "10 months of pregnancy" is not 10 natural months as she thought.

According to her, she was sitting on the couch eating fruit when her water suddenly broke, and she was so scared that she rushed to call someone to take her to the hospital.

When the hospital opened the finger, she could not help but think, this is not from ten months there are so many days, how suddenly to be born, the child this is premature, right?

Until the doctor told her clearly that "ten months of pregnancy" was not ten natural months as she understood it, and that she was already in her tenth month, and that the baby was no longer considered premature.

How many days is a "10 month pregnancy"?

Medically, the term "October Pregnancy" is based on a four-week, 28-day month, and 10 months of pregnancy, or 280 days ****.

From the moment of conception to the "ripening" of the fetus, the development of the fetus is completed, the end of the pregnancy, approximately 280 days of time.

Traditionally, the number of days in a natural month varies from month to month, for example, December of a year, some months are 28 days, 29 days; some are 30 days, 31 days.

If you follow the natural months to keep track of the different trimesters, it is very likely that the day count will be inaccurate and so on, thus affecting the smooth delivery of the fetus.

Therefore, by following the medical method of calculating the number of days between pregnancies, mothers will be able to accurately know their pregnancy cycle and the upcoming due date, regardless of the changes in the natural months.

Methods of calculating pregnancy

1. Menstruation method

The method of calculating the due date is as follows:

After the month of the last menstrual period -3 or +9, the date is +7, and the date of the due date can be obtained.

Pregnant mothers can also use the time of their last menstrual period to calculate the number of weeks they are pregnant. For example, 3 weeks pregnant is the date of the last menstrual period pushed back 21 days and so on.

It's important to note that using this method to project an accurate due date requires that the pregnant mom is having regular periods.

2. Fetal development projection method

On the occasion of the maternity examination, the ultrasound can detect the fetus's double cervical vertex, humerus length, and so on, and these data can be called an accurate basis for judging the week of pregnancy.

On the other hand, the degree of development of the fetus is affected by a variety of factors, the same gestational weeks of the fetus, there are some fetus development is too fast, and some are too slow, which will also affect the delivery time of the fetus.

3. Uterine height estimation

Medicine can also be used to estimate the exact week of pregnancy by testing the height of the uterus.

4. Ovulation Day Calculation

Generally speaking, it is calculated from the day of ovulation and pushed back 266 days to the expected date of delivery.

The prerequisite for using this method is to know exactly what day you ovulate.

Relatively speaking, the second and third of these four methods are more accurate, while the other two are subject to uncertainty, which can lead to deviations in the timing of the birth of the fetus.

Medically, a pregnancy that exceeds 42 weeks becomes an overdue pregnancy, and data show that the percentage of overdue pregnancies ranges from 5 to 12 percent of the total number of pregnancies, with a gradual upward trend.

There is a certain degree of risk associated with overdue pregnancies, so it is important for pregnant women to pay more attention, pay more attention, and listen to your doctor's advice throughout the pregnancy to avoid overdue pregnancies.
