When is my wife s due date? What is my due date?

If you have a baby in that month, your wife's due date should be around November 26, 2008.

Hello: The due date is calculated from the first day of the last menstrual period.

The due date is the number of months of the last menstrual period plus 9 (or minus 3) and the number of days plus 7

The last menstrual period is March 24, and the due date is December 31.

By May 25, she was 62 days pregnant, 8 weeks + 6 days.

The full-term pregnancy is about 280 days, and all births at 38-42 weeks of pregnancy are full-term pregnancy with spike oak.

Giving birth within two weeks before or after the expected date of delivery is normal.

Dear, the due date is calculated according to the day of the last menstrual period, the solar month is minus three or plus nine, the number of days is added to 7, and the number of lunar days is added to 14

Do the math yourself.

The entire pregnancy period is about 40 weeks, which is about 9 months and 7 days, and the expected date of delivery can be estimated by the time of the last menstrual period. The calculation method is calculated based on the first day of the last menstrual period, subtracting 3 or adding 9 to the month, and adding 7 to the number of days. However, the actual date of delivery may differ from the estimated expected date of delivery by 1 to 2 weeks, and if the date of the last menstrual period of the pregnant woman is not clear or the menstrual period is inaccurate, the doctor needs to calculate the due date on behalf of the pregnant woman.

So your due date is February 14, 2013.

The due date 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 about 28 days).

Based on 280 days (40 weeks), add 9 (or minus 3) to the month on the day of the last menstrual period, and add 7 to the date. For example, if the date of the last menstrual period is January 15, then 1 plus 9 equals 10, 15 plus 7 equals 22, and the due date is October 22.

If the last menstrual period comes on September 25, then 9 minus 3 equals 6, 25 plus 7 equals 32, and the expected date of delivery is June 32, but June is only 30 days, so it can be deduced that it should be July 2. This inverse algorithm is based on a 28-day menstrual cycle, so it must be corrected for the length of the individual's menstrual cycle.

Some scientists have made statistics, in fact, only about 53% of women give birth on the due date, so the due date is only an approximate date, not an accurate date of delivery.

My dear, you have to tell the answer about your last menstrual period, so that you can calculate the corresponding due date, calculate the formula, if not, you have to ask the question again, write down the last menstrual period clearly, and help the answer calculate it for you.

Gestational weeks are calculated by the date of their last menstrual period and are currently the most commonly used method.

1) Pregnancy and childbirth estimation formula.

This is the most common method of estimation, as long as you remember the date of your last aunt's arrival.

The specific calculation method is: month = last menstrual month -3 or +9 (can not subtract 3 to add 9) date = last menstrual date + 7 (if the number is more than 30, the number obtained after subtracting 30 is the date of the expected date of delivery, and the month is postponed by 1 month) For example: the last menstrual period is July 26, 2014, then the month = 7-3 = 4, day = 26 + 7 = 33-30 = 3, and the expected date of delivery is May 3, 2015.

2) Medical methods to estimate the expected date of delivery.

If you can't remember your last menstrual period anyway and don't know when you're likely to ovulate or conceive, your doctor will use certain medical methods to estimate your due date.

If the doctor does B overtime to measure the diameter between the fetal head, the length of the head and hips, and the length of the femur, the gestational age can be estimated, and the expected date of delivery can be calculated. Normally, only 5% of babies are born on the due date, and in most cases it will be a few days before or after the due date, so it is normal to give birth 2 weeks before and after the due date.

Since it is difficult for every pregnant woman to accurately determine the time of conception, it is medically prescribed 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.

The main calculation methods are as follows:

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 on 13 March 1999 and the due date was about 20 December 1999.

The last menstrual period was 28 May 1999 and the due date was approximately 5 February 2000.

Pregnant women can also be extrapolated from the first day of their last menstrual period to the 280th day of their due date.

Calculated based on 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.

Calculated from basal body temperature curve:

The last day of the low temperature segment of the basal body temperature curve is taken as the day of ovulation, and 264-268 days are extrapolated backwards from the day of ovulation, or 38 weeks are added.

Extrapolated from B-ultrasound examination:

The doctor can estimate the gestational age and calculate the expected date of delivery by measuring the biparietal diameter of the fetal head, the length of the head and hip and the length of the femur by doing B ultrasound (this method is mostly used as a doctor's B ultrasound examination and diagnosis).

Extrapolation from the time of the onset of morning sickness:

Morning sickness usually occurs at the end of 6 weeks of pregnancy, that is, 42 days after the last menstrual period, and the due date is calculated backwards to 280 days.

When was your last menstrual period? The month plus nine days plus seven is your due date, and it is normal to give birth about two weeks after the expected date of delivery.
