My last menstrual period was December 11, 2009, what is the expected date of delivery?

Hello! According to your last menstrual period, the expected date of delivery should be accurate September 18, 2010, b more than more than the problem should not be very big, but the mother's emotions will have an impact on the fetus, he will perceive this emotional change in adults. If there is no movement on the 28th, it means that you have misremembered the last menstrual period or the usual menstrual cycle is abnormal, and this can also be used to determine whether the fetus is mature or the approximate growth month with the help of B ultrasound.

If the fetus is overdue, the amniotic fluid is cloudy, and the fetal heart sound is accelerated, which will lead to intrauterine hypoxia in the fetus, so these two examinations in the hospital are normal, and the fetal heart sound 142 mentioned above is very normal. Please feel free to cooperate with the doctor. No matter how long it has been, there are no signs of labor, and a caesarean section should be considered.

I've heard of people who were born half a month after their due date.

Each person's situation is different. The landlord should follow the doctor's advice, B ultrasound will not have so many effects on the fetus. There are many people who are not in good condition during pregnancy, threatened miscarriage and the like, and it is not a three-day ultrasound for two heads.

You should relax your mind, it is not good to be anxious and angry.

If you are really in a hurry, you will have a caesarean section, which is the safest way.

Hello, I don't know if you remember the wrong time, if the time is correct, your due date is around September 18, 2010, and the due date has passed.

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.

Hello, the time of pregnancy is counted from the day of the end of the period. The due date is calculated backwards based on 280 days (40 weeks), then the month on the day of the last menstrual period is added by 9 (or minus 3), and then by adding 7 to the date.

Therefore, your due date is the number. I don't know how long your period lasts, let's say 6 days, then you are currently 118 days pregnant, almost 4 months. Wishing you good health.

Hello, the due date is November 18, 2013.

Last menstrual holiday + 280 days = due date.

Add one to the year and subtract nine from the month. The general estimate is that the difference between the front and back is 2 weeks in the normal range.

Hello! It can be rolled out based on your last menstrual period. Your due date is September 16, 2015.

Medically, a complete pregnancy period is 280 days, not 30 days a month, and the pregnancy is carried in October.

Also, the due date I just calculated is based on the assumption that your menstrual cycle is 28 days. If your menstrual cycle is 30 days, your due date will be 2 days later. Good luck getting pregnant!

Your due date is September 15, 2018.

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 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 fissure leakage and measures the diameter between the biparietal head of 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.

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.

Generally, the date of pregnancy is calculated from the first day of the last menstrual period, and the expected date of delivery is also calculated based on this day, and the rest is not important.

Calculation of the expected date of delivery.

Expected date of delivery month Month -3 on the first day of the last menstrual period (add 9 if it is under April) 11-3 = 8

Number of days due date The number of days on the first day of the last menstrual period +7. If it is more than a full month, the number of months is added to one month, and the remainder is the expected number of days.

Then your due date is probably August 25, 2010, I hope it will help you.
