Is October pregnancy really 10 months pregnant? Or 9 months?

The idea of pregnancy in October is due to the fact that the pregnancy cycle is 40 weeks. And there are four weeks in a month. That's ten months. If you follow the algorithm of 30 days in a month, it is more than nine months. So there is also a pregnancy in September. Said to be born in October.

The October pregnancy we are talking about is not actually 10 months of pregnancy, it is just a statement, and the general pregnancy is about 36 weeks. As long as the baby is full of weeks, it can be delivered.

About 9 months. In the actual clinical process, most pregnant women have basically matured by the time they are 8 months old. Pregnancy in October is a popular saying.

I think October pregnancy is a traditional Chinese medicine statement, a normal woman's menstrual cycle is: 28 days, ovulation occurs two weeks after the start of menstruation and two weeks before the start of the next menstrual period, so as to calculate the pregnancy time to calculate the number of days of pregnancy and the expected date of delivery, this calculation: 28 days * 10 months = 280 days, that is, 40 weeks, about 9 months.

As I understand it, pregnancy starts from the first day of the last menstrual period, seven days is a week, four weeks is a month, the whole pregnancy is 40 weeks, a total of 10 months, and it is said that the pregnancy is in October.

The 10th month of pregnancy is counted as a month of 28 days. A total of 280 days. Because the menstrual cycle is 28-30 days, most people are 28 days, so it is 10 months from the last aunt.

Because it used to be calculated by the lunar calendar, it was generally more than nine months, and it was only 10 months of the whole number.

That's 40 weeks and 280 days, and October is counted as four weeks per month... It's actually a little over nine months.

October pregnancy is said to be a lunar calendar, a month of 4 weeks, 28 days.

September speaks of 1 month and 30 days in the Gregorian calendar.

October is from abroad, and it is said that it is October, and it is also rounded, and September is our Chinese name.

Hello, I'm 55 open, 5 is 5 million of 5, open is open plug-in.

Brother, if you want to live a decent life, you have to have a little green on your head.

I also thought it was 10 months at the time, so I gave birth to a dragon baby, but it turned out to be a rabbit, and the whole gestation week was 40 weeks, that is, 9 months and one week, which was counted from the first day of the last menstrual period.

Normal: Nezha is still three years pregnant.

It is true that the pregnancy in October is actually only 9 months.

The pregnancy "October" is calculated as 4 weeks as "one month", not really 10 months, and the pregnancy period is 280 days, but in fact it is only 9 months. If you count it as 30 days per month, then it is only 9 months and 10 days. In fact, our natural month has 30 days and 31 days, so in fact, the pregnancy is only 9 months and 0 days.

Therefore, the formula used by doctors to calculate the due date is to add 9 or subtract 3 (decimal system) from the month in the date of the last menstrual period, and add 7 to the number of days, so that the calculated day is the due date.

Algorithm for October pregnancy:

1. The number of days of pregnancy, gestational week and expected date of delivery are all counted from the date of the first day of the last menstrual period. The due date is calculated as the number of months of the last menstrual period plus 9 (or minus 3) and the number of days plus 7.

2. The last physiological period of mu is September 25, 2011, and the expected date of delivery is July 2, 2012.

3. By December 3, 2011, 69 days pregnant, 9 weeks + 6 days, it is recommended to check on time during pregnancy.

4. It is about 280 days of lead month, and it is normal to give birth within the first two weeks or two weeks after the expected date of delivery.

5. From the last menstrual period to the expected date of delivery is 40 weeks, but there are two weeks of these 40 weeks, but just for the convenience of recording, these two weeks are the time from the last birth and balance period. If this time is removed, the actual time to conceive is 266 days, less than nine months.

Pregnancy in October refers to 40 weeks of pregnancy, and 40 weeks of pregnancy is the due date, and it is normal to reach the due date.

To be precise, the whole process of pregnancy is about 280 days, that is, 40 weeks. The gestational age begins on the first day of the last menstrual period, usually 2 weeks before ovulation or fertilization, and 3 weeks before implantation. Gestational age is usually 4 weeks as a gestational age unit, which is used to describe the growth and development of the fetus.

It is not necessary to give birth at the 40th week of pregnancy, and it may be early or delayed, which may be normal and not overly concerned, or it is possible to terminate the pregnancy early because of some comorbidities. Born after 37 weeks of pregnancy, the child born is full-term, which is sufficient in months.

Pregnancy process

Because after a woman is pregnant, from the last menstrual calculation, 280 days after the due date, 280 days is about 40 weeks, if the average distribution delay is ten months, a month has four weeks, that is, 28 days, so the pregnancy wants to use the month to indicate the time of pregnancy, it is generally recommended to use 28 days as the standard.

If the days are taken as the standard, it is easy to cause errors in the calculation of pregnancy time, which is not conducive to arranging the prenatal examination time and prenatal examination items, so it is ten months pregnant, not nine months pregnant. 37-42 weeks of pregnancy are full-term pregnancies, and it is normal for babies to be born during this period. After pregnancy, it is necessary to have regular prenatal checkups, pay attention to fetal movements, balance nutrition, and regularly do fetal heart rate monitoring to prevent the occurrence of fetal intrauterine distress.

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.
