Anyone else had due date changed after their 12 week scan when you didn't want it to be?

[ThatsNotMyDueDate]

Name changed for this as it is fairly specific and capable of outing me if I talk to anyone about it in real life.

I had my 12 week scan today. I should be 12+1. I was measured at 13+2 and told in no uncertain terms that this was the date that the NHS would be using and there was nothing I could do.

I am pretty upset about this. It would mean I conceived two weeks after we last had sex, and four days before I had pretty clear ovulation symptoms. I was (fairly patronisingly) told that sperm could live two weeks. Whilst theoretically possible, I think it is rather more likely that I ovulated when I think I did, and conceived two days after having sex. That would push my due date forward a couple of days, but nothing like the 8 they are telling me is now written in stone.

I wouldn't have a massive issue with this, but I've been well over 41 weeks with both my previous pregnancies (who also both measured a couple of days ahead but where the due date wasn't changed). I feel like I've effectively been told I'll only be allowed to go to about 40+6 before I come under induction pressure and have to argue about my planned homebirth.

After horrendous experience of induction with my first, I just can't cope with that hanging over me for the next six months for no good reason. I am fine with induction if I go genuinely far over, or because of any risk to the baby or to me. But the idea of going through that for no reason other than a number makes me want to cry (and in fact i have a bit). As does the idea of fighting against induction and for homebirth midwives to attend me. I find myself worrying about scenarios like taking out a loan for an independent midwife. Or begging for an elective section.

I just wondered if anyone had been in a similar situation. And also whether any midwives could shed any light on how difficult this situation is likely to get for me if I reach +14. I have heard horror stories of authorities simply sending ambulances for a hospital transfer when women who've refused to be induced finally go into labour.

Um, regardless of what the NHS think, your baby will be born on the day he or she will be born. Comfort yourself with that thought. My EDD was wrong with DS2. I knew damn well when he'd been conceived, and I was proved right when he was born when I said he would be

P.S. They can't do anything to you or your baby that you and your DH don't consent to.

This happened to me, when I was planning a home birth with DC2 and knew that I would go overdue (9 days over with DC1 and family history of 41+ week pregnancies.
On my maternity notes there was a space for 'agreed due date' which the midwife insisted on putting my (wrong) scan due date in. I said that I refused to agree this and said that she had to put in large letters that this was not agreed and my dates in as well. Or else I would do it myself. She reluctantly agreed.
At my '41' week appointment (when by my dates I was only 40 weeks) they wanted me to make an induction appointment. I refused and they said I had to go to the day unit to argue my case. I dawdled a bit with making the appointment and managed to go into labour myself and have my planned home birth. 10 days late by their reckoning, 2 days late by mine!
Let them say what they will about the scan date but don't 'agree' it. And if it comes to it at the end calmly explain why you are not as overdue as they think.
Good luck!

Oh I realise that they can't do anything to me. But I'm not planning on freebirthing and the idea that they might refuse to come out to a home birth is playing on my mind. As is the idea of my last weeks of pregnancy (this is definitely our last!!) being made a misery by pressure to induce.

If I had to guess (obviously a big guess, but the last two were almost identical), I would say that this baby will be born at about +16 based on my new date.

Cotton - Thank you for sharing that. One thing I have going in my favour is that my area don't push induction before 42 weeks. I'll take a look and see if the due date is 'agreed', because it bloody well isn't and I'll be writing that in myself if they've filled in a box without my agreement.

I don't think they can refuse to come out to you.

Youre not alone in the dating battle. Im very sure of when i concieved this dc (as we hadnt been having regular sex and i kno my ovupation signs) and at my 9 week scan i wad dated bang on. Then at 12 week scan they slapped another 6 days on the due date, but i think its just a big baby as was dc2, and me and my dp are very tall.
At first i wasnt bothered by this but when i started to think about it properly it has been worrying me as i am having a planned medical c section at 39 weeks. But goin by scan dates ile actually only be 38 weeks and i know sone babies end up in nicu if they are delivered too early.
Despite this the hospital refuse to alter my dd again so im goin to have yo try to push the c section date back when the time comes somehow.
This doesnt help much but just wanted to let you know that its not just your hospital being so stubborn with scan dates. Hopfully it will all work out ok in the end for us.

Yes, very similar to what happened to me with DS2. I was trying for a VBAC and very pissed off when they told me I measured a week ahead, as I knew it meant trouble once I passed my EDD. My DS1 was 7 days late and I had a feeling I wasn't going to go early!
I tried to fight my point but no avail. Apparently the 12wk scan is the gold standard and always right Sure enough I went overdue and had the c onsultants bullying me to agree to induction or another section. I refused on the grounds they had my EDD wrong! Went into labour naturally at 9 days past (16 days according to "their" dates) and he still had vernix on him and didn't look overcooked at all...
This time, baby measured a week ahead again. I told the (very nice) sonographer about my previous trouble with wrong due dates - so she stuck to "my" date! Just put me down at 12+4 on her report; obviously the measurement was off the chart, but hey ho. And here's the funny thing: EVERYONE accepted this. No one said, "Hey, this baby is measuring awfully big for dates," they just looked at the EDD and that was that And as they never ever correct the 12w scan date, I got to keep mine (even though baby was measuring big again at 16w and 20w scans).

My EDD was initially Sept 10th and then after the scan I was given 4th Oct even though I had had a positive test on New Year's Eve which according to the scan would have been before I was pregnant. Ds was born on September 15th weighing 7lb and MW felt he was slightly overdue.

Sorry to hear others in the same boat. It seems to be another case of 'we know best'

That's the thing isn't it. They are never going to change this. I told the sonographer that I couldn't be 13+2 as it would be an immaculate conception and she nodded and smiled and I thought she had listened. It was only when I got next door to the midwife that I discovered that the date was down as 13+2 and now set in stone.

Weird question for you op, but you do know that when working out a dd from ovulation/ date of dtd your going to be two weeks out because its customary to count the start of pregnancy as from the first day of your lmp and that's usually approx 2 weeks before ovulation?

This always makes you two weeks further along

Not a weird question sock, but don't worry, that's all accounted for in the numbers I gave. They are saying I conceived on day 6 of my cycle, I think it was 12 at the earliest.

Then you have obviously been eating super baby growing seeds

I asked because on every single antenatal appointment I've had this time round the waiting room has had at least one couple in it arguing about cheating because of the dd so I figured lots of people didn't know.

Ha ha. That's not a fight you want!

I really wouldn't care if I didn't think, based on my history, that it was likely to have implications for how easy or otherwise it is to get (obviously barring other complications) the homebirth I want.

Its such a frequent occurrence I've started playing guess the couple in my head.

Yeh they changed my dates too. I knew exactly when I ovulated and we had only dtd once that month so I know when I got pregnant but they still moved me forward 7 days.
So anyway my DS was born at 37+6 by nhs dates or 36+6 by my dates. I never said anything to them as I wasn't concerned but now I know babies come whenever they are ready.
I'm now 29+4 with baby no2 had again they have moved me forward 7 days.

I have been put 8 days ahead of my own dates. I am only counting from my lmp not ovulation but I still think that my date is probably closer to the mark. I am hoping for a vba2c so if I go overdue it will be a section as they won't induce me. When I mentioed this to my consultant she actually admitted that scan dates are thought to be plus or minus 5 days and pointed out my consent would be needed for any intervention so I felt reassured that I would be listened to if it gets to that point. It was nice to have my concerns listened to properly as up to then i was also brushed off and told that only the scan date 'counts'.

DS was IVF so you would have thought dating was irrefutable. They changed my EDD from 4th Sept to 10th. He arrived on 31 Aug regardless.
