LMP 7w but dating scan 5w5d

Another one of these posts but I'm out of my mind with worry....

I booked a private scan yesterday ( as had a previous MC but have two DC ) and I am pretty confident I am 7 weeks. I loosely tracked ovulation and was sure I felt ovulation pains, had EWM etc. However when I had the scan the sonographer dated me at 5w5d and no heartbeat was found, though everything looked good and healthy for this gestation. I am booked in for a re scan next Wednesday but of course, I'm fearing the worst and that I AM 7 weeks but stopped growing at 5w5d and I'm waiting to miscarry.

I feel 8 days miscalculation is too much and that it is a missed miscarriage.

Has anyone been through this, this early. I know it's common at 12 weeks to be dated slightly out but I thought this early on it was less common.

Thank you!

Hello.
I unfortunately went through a similar thing and it ended up being blighted ovum. I too was very sure of my dates as we were tracking and I was over a week out. The sack continued to grow and nothing was seen at follow up scans.
Sorry I cannot share a better experience. When I searched the internet when I had this, I did find people who had more positive outcomes and I hope this is the case for you x

If you are absolutely sure of your dates then I would be concerned yes.
Is it possible that your dates are out?
Ive had 6 miscarriages and I know how awful it is. I’m sorry you are going through all this stress.

I had this, a scan that early isn’t accurate for dating really. I went for a private scan when I thought I was 8 weeks and they measured me at 6.5. It worried me sick. I did end up having bleeding and some complications in the end with her being small and my placenta didn’t work very well towards the end, but my baby was ok and she’s now 1 years old. So it’s not always bad news

I don't think my dates could be that much out. I'm very sure of ovulation date but of course, implantation could have been later but not 8 days. The yolke sac measured 17mm and there was a 'baby' visible. It's so difficult to be positive as I feel so confident on my ovulation dates. X

@CPHB2021 unfortunately I'm going through the same. I went yesterday at what should have been 7+1 weeks so find an embryo of 5+2 with no heartbeat.

I know my dates are accurate as I track ovulation and when I got my test so I know mines bad news - going for a scan on Tuesday and will then do medical management. I really hope yours is a different outcome

So sorry that you're also going through this. It's just so rubbish and although I'm pretty sure that baby has stopped growing, the no bleeding/pain etc gives me some hope. I wish it was a clear answer yesterday instead of the most awful waiting game! X

I’m so sorry, I’m going through the same. Should have been 6 weeks 4 days measured at 5 weeks and confident of dates. I had an early scan due to spotting from around 6 weeks so I knew something wasn’t right. At about 7 weeks the bleeding started to get heavier with period cramps and my body is naturally miscarrying now.

It’s heartbreaking, it was my first pregnancy after 9 months TTC. The thought of going through TTC again fills me with dread, it consumed my life. We’ve decided not to track or test for pregnancy next time and see if we can take off the pressure.

I hope you have a better outcome than me. One thing I’ve found really helpful this week is talking about the loss a lot with my partner. It’s making it much easier to now to talk about and make sense of what’s happened. I normally bottle everything up but so glad I haven’t this time.

Sorry to hear you went through similar. I don't think this is BO as there was something inside the sac but no heartbeat so we can't be sure if the baby has stopped growing or if I'm measuring behind. It's such an awful, stressful time. Xx

I had this with my first child. Was certain of dates and early scan dated me a week behind. Said child is now 3 and jumping on the couch next to me x

Outliers · 04/01/2024 14:49

Could also be the case that implantation took place later than you think. Still quite possible that there's nothing to worry about just yet. Good luck

I am now starting to doubt my own dates....

I think all due dates are being calculated on a 28 day cycle which I do not have. This is my 5th pregnancy ( hopefully 3rd child ) so you'd think I'd be clued up!

My LMP was 15/11/23 with a 32 day cycle dates me at about 6weeks3days. If I ovulated or implanted late I suppose the scan dates could be correct!

Now I'm even more confused!

@Outliers you're a sensible voice on these threads. I've been doing some research on my own situation, I went at what I thought was 7+1 weeks and they gave me a measurement of 5+2 (2.5mm embryo).

However I track ovulation and actually I'd have been 6+5/6+6 and 2.5mm is actually 6+2. A heartbeat wasn't seen and I'm having another scan on Tuesday. I massively know the odds are against me - I know you'll tell me if I'm being silly!

I'm a firm believer in not worrying until they say you should be worried. I also say this as someone who was told to worry and everything ultimately turned out fine.

We ultimate guesstimate Ovulation and implantation, plus the growth rate can vary wildly in the early stages. Not only that, their measurements can also sometimes be off (they're still so tiny). When you get to 12weeks, no doubt measurement may change again.

I know that might not provide huge comfort, but hopefully everything's fine!

This happened to me too a couple of months ago. Early scans were nearly two weeks out and the pregnancy carried on until 15 weeks when I had to have surgery to have everything removed. I did a lot of research to prepare myself as I was certain of dates in the beginning and I think I just had a feeling too. The waiting is awful but as other people have said there are positive outcomes. Equally I know someone who’s dates and measurements were out and by 12 weeks it was fine x

ThelastRolo20 · 09/01/2024 17:51

@CPHB2021 I know you have your scan tomorrow, wishing you all the best for it.

I went for my scan today and although I'm still tracking around 1.5-2 weeks behind, baby has grown and there is a strong HB! Getting re scanned in 2 weeks but they didn't seem as concerned as I feel about the date discrepancy.

loopyloos · 31/01/2024 07:42

Hello, I’m just looking for some sort of advice really. I had a private scan which dated me 5w5d and no hb. Referred to nhs who scanned me and dated me 5w4d no hb. He said everything looks good with yolk sack and fetal Pole. Rescanned in a week to check for growth. Anyone had this? What are my chances? I’m going out of my mind :(
