There is a saying among the people that conceived in October , is this true?

Gestational age of 37 to 42 weeks is full-term, so it is usually less than 10 months.

As the saying goes, "October pregnancy" means that you have to be ten months pregnant to give birth to a baby. But the average pregnant mother has given birth to a baby in more than nine months, what is going on?

I heard the mother who came to the Korean Pregnancy Club to take maternity photos say, "It will be nine months in just over a month, and it will be unloaded soon." "Why not ten months? Today I will talk about the "October" of "October pregnancy".

Everyone has a misconception, that is, most people think that every mother gives birth to a baby after ten months of pregnancy, and this "October" is the meaning of the baby's full-term month.

So what is "full-term"? The time of term and the due date are very important things for pregnant mothers. In medical science, the time of term and the expected date of delivery are calculated from the first day of the last menstrual period.

The "month" in "October pregnancy" refers to the month of pregnancy, not the month we often call it. As long as the pregnancy is full of 37 weeks, that is, the baby born after 37 weeks (including 37 weeks) is full-term, and the baby born earlier than 37 weeks is called a premature baby. If the menstrual cycle of the pregnant mother is 28 days, then 280 days of pregnancy is equivalent to ten gestational months or ten menstrual cycles, so there is a saying that the pregnancy is in October.

In fact, the duration of delivery is often 1 to 2 weeks away from the due date, which is only an estimate.

Seeing this, I believe that expectant mothers should know what is going on with "October pregnancy", and there will be no more "October" and "September" stupidly unclear.

The "month" of October refers to the menstrual cycle. Normally, the average menstrual cycle is 28 days, the ten menstrual cycles are 280 days, and the pregnancy is 10 months, that is, 280 days of pregnancy, that is, 40 weeks, medical students, from the first day of the woman's last menstrual period, plus 280 days, that is, the expected date of delivery. In order to accurately grasp the growth and development of the fetus, doctors will talk about how many weeks and days of pregnancy, and in order to avoid confusion with the natural moon phase, they will not say how many months of pregnancy.

In October of pregnancy, women should pay attention to strengthening nutritional supplements, pay attention to rest, do not stay up late, and maintain a positive and good attitude.

October pregnancy, is a fertilized egg after 10 months of development and differentiation, the formation of the fetus process, October refers to the initial fertilized egg to the final delivery is about 266 days (that is, 38 weeks), but because many pregnant women can not accurately determine which day of pregnancy, so for the sake of convenience, medical regulations on the first day of the last menstrual period from the beginning of the count, so that the whole pregnancy has two more weeks, so it becomes 280 days. Originally, there were 7 days in a week and 30 days in a month. But for pregnant mothers, 28 days is a month, so 280 days becomes "ten months".

That's why the phrase "conceived in October, born in one day" came from. The first method: Calculated based on the last menstrual period.

This method is the most commonly used. If your menstrual cycle is regular, menstruation occurs every 28-30 days, and the last menstrual period knows the exact end time, then the simple way to calculate the due date is: from the first day of the last menstrual period, the number of months plus 9 or minus 3, and the number of days plus 7, is the month and day of the due date.

For example, if the last menstrual period is January 5, 2007, then the expected date of delivery is October 12, 2007 (1+9) (5+7) day. The second method is calculated by the date of the onset of the first trimester reaction.

This method is suitable for expectant mothers with irregular menstrual cycles or when expectant mothers forget the time of their last menstrual period and only remember the time when early pregnancy reactions such as nausea and vomiting appeared. Because the general time of first trimester reaction is about 6 weeks, the expected date of delivery = the date of first trimester reaction + 34 weeks. The third method:

Calculated according to the date of fetal movement. If the expectant mother can't remember the time of her last menstrual period, she can't remember when the first pregnancy reaction appeared. Then, the baby's date of birth can also be calculated in this way.

In general, fetal movements begin at 18-20 weeks after pregnancy, and this method is suitable for expectant mothers who have given birth for the first time and mothers who have already given birth. Then, the calculation method is: due date of primiparous mother = date of conscious fetal movement + 22 weeks; Due date of multiparous women = date of conscious fetal movement + 24 weeks.

The fourth method: Extrapolation based on B-ultrasound examination. This method is mostly used as a doctor's ultrasound examination.

During pregnancy, expectant mothers will go for a B-ultrasound examination to check whether the baby is healthy, and there will always be some data on the examination report that you can't understand. However, based on these data on the ultrasound sheet, the doctor can estimate the baby's gestational age and calculate the expected date of delivery.

October refers to about 266 days (i.e. 38 weeks) from the initial fertilized egg to the final delivery, but because many pregnant women cannot accurately determine which day they are pregnant, for the sake of convenience, it is medically stipulated that the first day of the last menstrual period is counted from the first day, so that the entire pregnancy is two more weeks, so it becomes 280 days.

Pregnancy in October, once delivery, the human pregnancy period from the successful start of fertilization to delivery is about 10 months, in fact, the real time is not 10 months. The meaning is: something is well prepared and will come naturally. Agreed: melons are ripe.

At 40 weeks of gestation, the fetus matures in the mother's body and is about to give birth. From the expected date of delivery: from the first day of the last menstrual period, the month is minus 3 or plus 9, and the date is added by 7

The actual date of delivery can be 1 to 2 weeks different from the expected date of delivery. It is the time when the fetus is in the mother's body, that is, the legendary October pregnancy.

October pregnancy is a process in which a fertilized egg develops and differentiates after 10 months to form a fetus.

It takes 280 days, or about 10 months, for the human body to reach maturity from the birth of a new life. Describe the hard work of the mother.

It takes 280 days, or about 10 months, for the human body to reach maturity from the birth of a new life.

=-=。Your mother will give birth to you, and she will be ten months pregnant.

The pregnancy in October mentioned by the doctor is calculated according to weeks, that is, 4 weeks and 28 days are counted as one month, and 40 weeks of pregnancy is exactly 10 months.

But according to the normal month algorithm, 30 or 31 days in a month is nine months.

However, no matter how you calculate it, it will take about 280 days to conceive.

Normally 9 months pregnant, I'm about the same. Thanks for adopting!

"October pregnancy" is a Chinese idiom derived from the ancient way of calculating the time during pregnancy.
