How far off was your due date from the actual birth date?

I’ve been planning this for 2 years and I’m going to try and conceive early 2018 so I can have a baby born after September (so they’re the oldest of their school year).

Through fertility calculators, it states that if my last period is the 26th of December, fertilisation would probably happen on the 8th if Jan and the baby would be due 2nd October.

How accurate were your due dates were compared to the estimate? And did you use an ‘online due date calculator’ before hand and was these results fairly accurate to the actual birth date?

Dd was due on Xmas day. She was born 8 Jan, but equally could have been born 11 December and still be full term.

I wouldn't plan too precisely, maybe don't ttc until 1 Jan?

DD due 11th Nov, arrived 26th. LMP date was 14th Nov but was moved back 3 days.

DD was 10 days early though 12 days early going by original due date based on LMP

the only thing predictable about due dates is their unpredictability! Both mine were 12 days late according to dating scan. Ds1 looked like it and dd2 really didn't!

I had one born on due date, two born a week late.

UnalliterativeGeorge Sat 18-Nov-17 15:25:45

Both mine were born at 37 weeks. Impatient children!

DD1- they moved my due date back 8 days from my LMP date. She arrived 10 days before due date (2 days after LMP date)

DD2 - they moved my due date back 2 days from my LMP date. She arrived 4 days before due date (2 days before LMP date).

Dating scams are so technologically forward now that they are fairly in terms of gestational age but it doesn’t determine whether baby will be early or late.

My cousin was born 6 weeks early. Her birthday is 29th August. Aunt also planned dates around school year. Oops!

My first was due the 2nd of June arrived the 15th.

Bobbiepin Sat 18-Nov-17 15:39:21

LMP 2nd Jan, EDD by dates was 9/10, scan pushed that back to 26/10, DD arrived 24/10.

If you are using online calculators be mindful to use one that takes into account your cycle length. I had a longer cycle than average so the 40 weeks woudn't be an accurate representation of when I actually conceived.

My 1st due 28th Feb, born just after midnight on March 1st.

2ducks2ducklings Sat 18-Nov-17 15:42:37

My daughter was a day late (induced on due date) my eldest son was 12 days late and my youngest was 4 hours late.

BikeRunSki Sat 18-Nov-17 15:43:16

18 days early
7 days early

Wanderwall Sat 18-Nov-17 15:43:52

I was almost bang on with both.

JellyJ Sat 18-Nov-17 15:44:08

One day early, 6 days early, one day late. But don't get too hung up on the September thing. It's not the only factor in how well they do at school. I feel that my July born child has not had any disadvantage and my September born one has not had any advantage. If it is important to you, err on the side of caution and aim for October or November.

GlennRheeismyfavourite Sat 18-Nov-17 15:46:05

Take care - I massively screwed this up! Wanted a September baby - she came at 38 weeks on 31st August!

yikesanotherbooboo Sat 18-Nov-17 15:46:12

Due date *2

FlappyRose Sat 18-Nov-17 15:46:27

Due 21st February, born 12th January. So not close really.

idpreferanegroni Sat 18-Nov-17 15:46:29

14 looooong days after due date!

Catalufa Sat 18-Nov-17 15:46:50

My last period started on 30 Nov and DC was born on 13 Sept (7 days late).

ShowOfHands Sat 18-Nov-17 15:49:33

I conceived on December 31st and was pretty keen to give birth in Sept over August. My waters broke on September 1st (ds born on the 3rd).

Ninjakittysmells Sat 18-Nov-17 15:52:53

Ds was born 9am on his due date - couldn’t have been more accurate if I’d tried!

NickMyLipple Sat 18-Nov-17 15:53:48

Just out of curiosity if it doesn't work out in the first 3 months will you wait another year?

flapjackfairy Sat 18-Nov-17 15:57:17

Ist child arrived on his due date . 2nd was 2hrs into the day after her due date . 3rd 5 days early !

fucksakefay Sat 18-Nov-17 15:58:56

Due date just tells you when 40+0 is based on last period. May be adjusted on scan, however a 12 week scan has a +\- 7 day accuracy. This still only tells you the 40 week mark. Normal birth is anywhere between 37-42 weeks.
My birth dates were 41+3, 42+2 and 37+6.
