How many weeks is the entire pregnancy?

Pregnancy is a big happy event for many young couples, but because they are novice parents, they have no experience and don't know how to calculate how many weeks they are pregnant. If they want to calculate the due date, they need to arrange everything and go to the hospital for "unloading". They can find out the pregnancy time through B-ultrasound examination, or calculate it according to the pregnant woman's due date. So, how many weeks does the entire pregnancy last? Pregnancy has a relative cycle. The fetus will have different development at each stage of the entire pregnancy. To understand the condition of the fetus in each cycle, the fetus's due date, etc., the best way is to calculate the pregnancy time.

How much does it cost to get pregnant?

1. Calculate based on the last time of your period. Add 9 to the month of your period to get the month of your due date, and add 7 to the day of your due date to get the day of your due date. For example, the last time I had my period was on February 13th, and my due date is November 20th. It is very simple to calculate the expected date of delivery in this way. Although it may not be very accurate, it has certain practical value.

2. Calculate based on B-ultrasound examination results. Some people do not know the last time they calculated their due date, so they can see a doctor for an ultrasound examination, and roughly estimate the gestational age based on the length of the fetus, and then calculate the pregnancy time and determine the actual due date. At present, this method is widely used in clinical medicine.

When estimating the time of pregnancy, some people think that it should be counted from the time of the last intercourse. Now you have to try your best to think about the time of previous intercourse. In fact, it does not start counting from the day of intercourse, but from the time of the last menstruation. As long as you can remember the day of the last menstruation, you can know the current pregnancy time. The due date is usually calculated by adding 9 to the month of the last menstrual period and 7 to the day.

How to calculate the number of days of pregnancy most accurately

I believe that many pregnant mothers are eager to get the most accurate pregnancy time calculation data. If accurate and reasonable data cannot be obtained, it will definitely affect the daily affairs of pregnant mothers. Many pregnant mothers hope to know when they will give birth. After knowing this data, they can adjust their working hours in time and get enough rest and prepare for delivery at that time.

After many clinical trials, it was found that the normal delivery cycle is 280 days starting from the first day of the last menstrual period. The pregnancy period is 10 months, each year is 28 days, and pregnant women will give birth between the 38th and 42nd weeks of pregnancy. Because each pregnant woman's menstrual cycle is different, the estimated delivery date will have a deviation of one to half a month. This deviation is within the normal range. The general calculation method is: add 9 or subtract 3 from the month of the last menstrual period, and the result is the number of months of the delivery period. Add 7 to the day level, and the result is the number of days of the delivery period. This calculation method can be used to calculate the most accurate number of days of pregnancy for pregnant women.
