What gestation did you give birth?

Curious to know! For those of you who are 100% sure on the date of conception, what gestation did you give birth?

I’m sure on my due date, however the NHS have put me a week earlier which is obviously impossible. I imagine baby is just measuring bigger than expected. I’m sure I’ll be encouraged to induce or book a c section if baby is ‘overdue’.

When I’m ‘40 weeks’, I’ll actually be 39 weeks based off when I know we conceived.

So, did your baby come on the due date you calculated or were they early/late?!

Yes it would have been 38+5 by my own dates although weirdly I haven’t thought about it like that until now.

I think they say babies can come between 37-42 weeks. It’s not one size fits all and it’s a bit frustrating when the NHS make you feel like you’re crazy haha. Also, babies come in different shapes and sizes regardless. Just because the baby was bigger or smaller than expected, doesn’t suddenly mean the due date should jump! My partner is a very tall man so i understand why this baby is measuring a week ahead.

They do say babies can come from 37 weeks! So you were 38+5 according to your own dates?

My dates measured up with size of baby, gave birth at 42weeks after 3 failed inductions

BingBongBoo86 · 07/05/2025 22:02

My due dates were way off about birth dates.

DD1 due 25th June, born 7th July - induction. Still don’t know when she was conceived.

DD2 due 12th September born 28th September - induction. Was sure of dates and NHS matched ovulation day.

Was disappointed not to ever experience going into labour naturally but I’m convinced my body either doesn’t know how to do it or I have longer than normal pregnancies. My cervix is always high, don’t progress quickly and labour is long and painful.

Felt some pressure to be induced. Held out for longer with my second. There was no hounding though, I had a very calm sensible conversation with a doctor who informed me of the potential dangers of going over 42 weeks. I said I wanted to wait another couple of days but then lost my nerve and went in for induction. Interesting, the doctor I spoke to said she had delivered babies at 43/44 weeks but didn’t recommend it. Think my 2nd would have probably been an October baby but I couldn’t cope with the ‘what ifs’. Incidentally, my placenta with my second was heathy looking and baby coild have stayed in for longer according to midwife.

Both of my pregnancies were dated a week later than I thought I was due (a more inexact science in those days but I was fairly certain of ovulation even so). First baby born at 40+13, second at 40+8. Both still had vernix.

GhostHunterPlay · 07/05/2025 21:54

I was given 2 dates as to when my son would be born. My GP told me to prepare the nursery for some time in October, whilst the hospital predicted that I'd give birth on September 8.
He was actually born on September 3, 1991, meaning that, according to the hospital, I was 39 weeks and 5 days when my son was born.

ClearHoldBuild · 07/05/2025 21:50

DD - Due 10 May, gave birth 17th May
DS - Due 9 July, gave birth 4 July
no issues with either birth, labour was approx 5/6 hours both times.

NapTrappedAgain · 07/05/2025 21:46

I was in this exact situation. Due date moved forward by a week at the 12 week scan. I was 100% sure on conception date as there was only one option that month and I’d had early scans due to previous issues at 5 weeks and 6 weeks and all was on track at those, measuring behind at 5 weeks if anything. Like you, I was a bit concerned I’d be induced when they think I’m overdue but I’m not by my dates which I was 100% sure of.

Anyway I ended up giving birth at 39+5 NHS dates so maybe they were right. Still can’t work out how that would be possible though!

With my first I had been using bbt to track ovulation. I ovulated on day 26. So when we went for our first midwife appointment she asked for my lmp. Instead I showed her my tracker and we worked out when I’d ovulated so we used that as a guide to decide on my due date. When we went for my scans, the dates matched perfectly to my adjusted cycle. My waters broke in the early hours of my due date and he was born the next day.

With my second, she was an ivf baby so you’d think the dates would be super accurate. But the nhs 12 week scan changed my due date by a week (said I was 13 weeks when I knew I was only 12 weeks). From this point on, my baby always measured small for dates and I was induced at 38weeks as she’d slowed down growing (I had GD so this complicated matters). She was only 5lb 6oz, which matches with my original dates (so she was actually 37 weeks). But despite this, she caught up easily and is now 50th percentile in everything.

It's frustrating OP, isn't it? I knew exactly the one day we had unprotected sex. From my period to the day prior, I had been on holiday with my parents, so absolutely no chance of "accidents" earlier that month. First scan put my dates forwards, and then second scan sent them forwards again. I kept raising this with the midwives, as I'd been moved forwards by about 10 days, but they really didn't care. I had an ELCS at 38w 6d, but I think I was closer to 36w, which did scare me. DD was fine, but on the small side. Long though, always has been.

Part of me does understand that many women either don't know, don't understand or have reasons to lie about conception, so medics need to be careful BUT I don't understand why they do not listen at all to concerns and insist you are mistaken. Surely it is a risk to the baby's health?

It is so frustrating. I mean luckily, the pregnancy isn’t high risk. But it’s well known they don’t like women to go over due anymore due to the increase risk of stillborn and other complications but I won’t actually be overdue when they think I am. We shall see what they want to do if and when I reach 40 weeks!

I’ve tried, unfortunately they won’t change the due date. I believe I’m due on the 10th but they say the 3rd

Hm. Can you get a midwife onside?

Good luck whatever happens.

Madden21 · 07/05/2025 21:34

MissyGirlie · 07/05/2025 21:30

in your shoes I would explain ASAP that you know the date of conception and get the due date changed in your notes.

Being insistent many years ago almost certainly spared me being induced as I went well over even by my own (very precise) date. As it was I had a quick labour and a straightforward delivery.

And the baby was huge - which might have been why the sonographer's dates were out!

@GetDressedYouMerryGentlemenIt’s really interesting. But basically if and when I get to ‘41 weeks’ and they start hounding me I’ll be politely declining unless there is a serious concern for myself or my baby as I know I’ll actually only just be 40 weeks.

Mumofsoontobe3 · 07/05/2025 21:28

37+1 with DC1, induction. I believe I was only 36+1
38+1 with DC2, waters broke naturally, I believe I was bang on dates
Currently pregnant with our final DC and I’m 26+2 according to NHS dates - we conceived on fireworks night 100% - we only know for sure because DC2 was 7 months old and in his own room for the first time 🫣

40+6 for DD, although her original due date was the 10th (which made sense), then because of her measurements at the 20wk scan they put it back to the 5th. We were sure the 10th was the right one, and she was born on the 11th. On the 50th percentile for everything too so I'm not sure how she was measuring so big at 20wks! They made it sound like we had some gigantic baby on the way...

38+5 for DS. His due date also got changed but only from the 17th to the 18th, but obviously either of those made sense. He was in a hurry to be born though!

Thank you for sharing!

Sorry if I've missed this from a PP, but are you accounting for the fact that you are counted as 2 weeks pregnant at the time of conception @Madden21 ? Day 0 is the 1st day of your last period.

Yeah I am. I have a long cycle also, 42-45 days. They don’t care though and I’m pretty sure the date they’ve given would be based off a shorter cycle.

Women in my family seem to have long pregnancies, my mum did and so did my sister. I was 41+5 for my first, went into natural labour and 42 weeks for my second I was induced at that point. My dates where fairly solid as my periods where regular and I new when I conceived but they put my first pregnancy forward by two weeks. I was a bit baffled by that at the time as I would have conceived when I had already tested positive so I didn't really believe the dates the NHS gave me. They where more accurate with my second and aligned with my dates.

How many weeks were you according to NHS dates?

36+1 for me. She was 100% conceived on my 40th birthday. I still blame the white port in Lisbon 20 years on.

It’s super interesting. When was she born according to the NHS dates?

Have you factored in the (roughly) two week of not being pregnant yet that are counted in the system of dating from your last period?

As I.have said earlier in the thread no one pushed me for sweeps or induction before 42 weeks although mine was born 15 years ago. You can refuse intervention and say you are happy to wait for natural to take it's course but by the time you are lugging a fully formed baby about you might feel differently about hurrying things along. I was total over being pregnant by 38 weeks, bored witless by 40 weeks and begging my midwife to step in at 41 weeks.

They’ve dated me earlier than possible not later.

& I will be refusing intervention. This will be my 4th birth (but first time I tracked ovulation) so it’s the first time I’m 100% sure on conception. We only dtd twice that month and it was 2 days in a row. I’m very sure I know when I’m due.
