The calculation is based on the entire gestation period of 280 days, and the specific method is: the expected date of delivery month The month of the first day of the last menstrual period is +9 or -3 [before April +9, after April -3], and the number of days of the expected date of delivery The number of days on the first day of the last menstrual period +7. In this way, the calculated time is the due date.

It should be on August 22, and it is medically stipulated that the expected date of delivery is calculated from the first day of the last menstrual period, and the entire pregnancy period is 280 days, 10 gestation months (each gestation month is 28 days). Pregnant women give birth within 38-42 weeks of gestation, both at term. Since the length of each woman's menstrual cycle varies, it is normal for the estimated due date to differ from the actual due date by 1-2 weeks.

Get ready.

Expected in 2013. August. 22 or so, but it is not ruled out that there will be a possibility of premature birth, so it is necessary to pay attention in advance, a few days before the labor should be guarded often, try not to go out, to avoid accidents, I wish you a cute and healthy baby...

August 22, 2013 This is the date of 40 weeks, and 37-42 weeks are normal.

Hello, medically stipulated, the expected date of delivery is calculated from the first day of the last menstrual period, and the entire pregnancy period is 280 days, 10 gestational months (each gestation month is 28 days).

The month of the last menstrual date is added by 9 or minus 3, and the feast is the number of months of the expected date of delivery; The number of days plus 7 is the expected date of delivery. For example: Your last menstrual period was on December 24, 2009. Month.

12-3=9。Day 24

7=31 (1 month and 1 day).

Your due date = October 1, 2010.

Calculated on the first day of the last menstrual period, the month is minus 3 or 9, and the number of days is added 7 (lunar calendar plus 14), and the date obtained is the expected date of delivery. For example, if the last menstrual period is May 15, 2018, the expected date of delivery is February 22, 2019, and the birth is within one week before and after the expected date of delivery, it is normal for you to be born. If you do not remember your last menstrual period or have no menstruation during breastfeeding, or if you have irregular menstruation, you can roughly determine the due date based on the first trimester reaction, the time when the fetal movement began, the height of the uterine fundus, and the size of the fetus.

If necessary, the fetal double parietal diameter can be measured by B-ultrasound to estimate the expected date of delivery, which is relatively more accurate.

Dietary precautions in the third trimester:

In the third trimester, expectant mothers enter the final sprint stage, and the storage of nutrients is particularly important for expectant mothers. A safe, healthy and reasonable diet is a necessary prerequisite for the healthy birth of a fetus. Combined with the nutritional characteristics of the third trimester, the diet of the second trimester should be adjusted accordingly.

1. Diversified dietary requirements: In the late stage of pregnancy, expectant mothers not only need to supplement calories, but also pay attention to the supplement of nutrients such as high-quality protein, iron, calcium and vitamins, and can adopt a diet of eating less and more often, which can increase to more than 5 meals a day. Do not take a large amount of supplements to avoid excessive obesity and macrosomia (the weight gain of expectant mothers during pregnancy should not exceed 15 kg).

2. Supplement sufficient calcium and iron to help the fetus's teeth and bones calcify well and prevent anemia of expectant mothers, you can eat more kelp, seaweed, dried shrimp, sesame, animal liver, eggs, fish, etc.

3. Increase the intake of plant-based proteins, such as beans and soy products.

4. Reduce the intake of foods with high sugar content, such as fruits, sugar, honey, etc., so as not to overgrow the fetus and affect the smooth delivery.

5. Eat more foods with high nutritional value and small size, such as animal foods; Eat less foods with low nutritional value and large volumes, such as potatoes, sweet potatoes, etc.

Result: Your due date: August 19, 2017.

You are pregnant: 124 days.

1) Calculated based on the last menstrual period:

The month of the last menstrual date plus 9 or minus 3 is the number of months of the expected date of delivery; The number of days plus 7 is the expected date of delivery.

For example: the last menstrual period was February 1, 1985, month 2 + 9, date 1 + 7, due date = November 8 (85 years).

The last menstrual period was April 15, 1985, months 4 - 3, date 15+7, due date = January 22 (86 years).

2) Calculated according to the date of fetal movement:

If you can't remember the date of your last menstrual period, you can calculate it based on the date of the fetal movement. Usually fetal movements begin at 18-20 weeks after pregnancy.

The calculation method is as follows: the day of fetal movement plus 20 weeks for primiparous mothers; In multiparous women, the day of fetal movement plus 22 weeks is added.
