What is the best way to calculate due date and estimate delivery date?

It is really complicated. The simple calculations listed below based on a fixed addition from your last menstrual period or those used by most online calculators are terribly inaccurate. A lot of recent research has indicated a number of other variables to consider. (See the page links, further down this page, listed under Related Links).

This is how to calculate your due day. The due month is: your LMP month + 9. The due date is: your LMP date plus 7. For example, if your LMP was 3/10/95: 3 + 9 = 12 (Dec), 10 + 7 = 17 (17th day). If the added month exceeds 12, then you subtract 12. For example, if you LMP was 6/20/95, the month will be (6 + 9) - 12 = 3 (March), and the date will be 20 + 7 = 27, so your due date will be 3/27/96.

  • There are loads of methods and calculators out there but their accuracy is limited.
  • I was always taught -3 +7, if your LMP was 10/11 you -3m= 7/11 and add 7d= 7/18.
  • You can always use an online due date calculator. See the page links, further down this page, listed under Related Links.
  • Maybe I don't get it but what is all the maths above? Why would you do all this if someone else would do it for you?
  • Due Date Calculation

Pregnancy, on average, lasts 267 days (38 weeks) from conception. If you positively know your conception date, you can add 267 days to it for your due date. The following formulas can also tell your EDD:

Date of the first day of your last period + 281 days = due date
Date of the first day of your last period + 7 days - 3 months = due date
The methods here are based on the average 28-day menstrual cycle.

When did you conceive if your due date is March 12?


There is no way to tell the exact date, but an estimated date would be around December 19th.

Alternately, according to your due date, you conceived around 11th January. However, some women ovulate later than others so give and take +/- 5 days.

Visit this site below and scroll down till you get to the table. This will give you an accurate reading based on the first day of your last menstrual period and or due date.

What is the importance of months?

Out of the whole main number System everything is even.

Example, The Number one contains ,Tenths (0.1), Hundredths (0.01), thousandths (0.001).

In essence half of 1 it is simple and and Easy to Half (0.5) quarter it (0.25).

Now The whole Hindu Arabic Number System (this System) Is quite Accurate and easy to do because nothing is disoriented and odd.

The only thing that breaches this system and yet has to fit in is Time, minutes (60 seconds)

hours (60 minutes) a day (12 hours) a year (12 months).

Now months are the tricky ones because the the Vary in 28 days, 30 days, 31 days,

Without Months, the whole time system crumples since holds most of every bit and piece.

The reason why months are larger and smaller than another is Because when the earth revolves around the sun some parts are closer to the sun than others that's why we get seasons (summer we are closer to the sun , winter further away.)

That is why Months are Important.

Pregnancy Tests

How many weeks does it take to know if you are pregnant?

For a home test you need to be at least one day late starting your period. I don't know for a doctor given blood test.

For a doctor given blood test they suggest that you wait 3-5 days after your missed period. However, the test may be taken as soon as you suspect that you are pregnant.

Does a blood test for pregnancy also tell you how far along you are?

Based on how high the hcg level is, a good guess can be made about the length of your pregnancy. Your doctor should do a vaginal sonogram to determine gestational age thus determining the due date.

However, higher levels of the hormone HCG are often found in the case of multiples. (twins etc.) Lower levels of HCG may indicate the egg has inplanted in a place other than the uterus. (Fallopian Tube = Etopic Pregnancy)

Can you not know you are pregnant at 20 weeks?

I know of a couple of girls who did not know they were pregnant until they were in labour. So i guess you could be and not know. Although i dont understand how women could be pregnant and not know. You would think they would feel the baby move at some point.

Labor and Birth

Could a woman have labor induced 2 weeks early because of backache or is it more likely that she fibbed about how far along she was?

I don't think they would induce someone because of back pains. But two weeks early isn't always early. The due date can be off by two weeks before or after. It is an educated guess. I can't guess if she fibbed about the due date or not because two weeks isn't a lot when counting the due date.

I am 43 years of age I had my 1st pregnancy a year ago... My doctor induced my labor because of lower back pain... Regardless of when this women had sex, due dates are not exact a women can go into labor up to 3 weeks (37 weeks pregnant) befor her due date or 2 weeks post due date (42 weeks) and still be considered full term.. If the guy is so worried that the baby isn't his then maybe he should get a paternity test done... If He has already put his name on the birth certificate, and the baby isn't his then he'll be legally obligated regardless of the child's paternity..

I was with my last one. I couldn't sleep and they reasoned that it was better to induce me and me have the energy to push him out, then to keep him in and have me too exhausted to do it.

I apologize for not mentioning that this woman was 42 years old at the time of conception, and the man that she claimed was the father had used a condom the one time they had sex. Do you think that would make a difference? I have always heard that a physician wouldn't dare induce labor on a high risk pregnancy. Thank you for your answer!

Actually a physican will induce labor if he/she chooses to regardless of it being high risk or no. I have several friends who have had preeclampsia and/or gestational diabetes and the majority were induced. Now the behavior of this particular lady is rather suspicious. But honestly, as a pregnant woman being 39 weeks, my doctor has already suggested stripping my membranes to help me out since my child has been dropped for some time and my pubic bone and entire pelvis is so sore I cannot sleep for more than 2 hours a night.
