Has anyone had an embryo measure weeks behind and turn out OK?

[AncientandPregnant]

Just wondering if anyone has stories of situations similar to mine, whatever the outcome.

I know I am 8 weeks today.

When I should have been 6+2 I had a scan and there was a small gestational sac and no yolk sac or embryo. They said I was about 4-4 and told me to come back two weeks later.

Yesterday I returned. I should have been 7+6. This time they found a larger sac, a yolk sac and a 4mm embryo with a tiny flicker that they said wasn’t necessarily a heartbeat.

They said I was 6 weeks on the dot and that the progress over two weeks was fine as my dates were clearly wrong.

I had sex once the month we conceived and tested positive 12 days later. By their new dates I would have not been pregnant yet on the day I tested positive. My dates can’t be wrong.

They want me to go back in two weeks but I’m so sure of my dates that I see no hope at all. I also have v few symptoms which is unusual for me and I am an age where 50% of pregnancies miscarry.

Has anyone experienced anything similar? What was your outcome?

Unfortunately I've got no feedback to offer, I'm
In the same situation as you so I'm looking for some positive stories too.

Wishing you the best luck xxx

@octobersky I am so sorry you are going through similar. How many days out are your dates compared to the scan?

Any change you ovulated late and HCG gets in your system really early? I’m 35w now and got a positive test over a week before my missed period

@lizzieanna99 given I only had sex once there isn’t a lot of leeway on dates. I suppose the sperm could have lived a whole 5 days inside me before conception, and conception could have been those 5 days later due to an incredibly late ovulation, and I could then have been in the rare group who gets a positive 7 days after conception BUT even with all those rare occurrences I’d still have be 7+2 yesterday and not 6+0 as the scan said.

@AncientandPregnant I should be 7 weeks today, I'm measuring 4.5 - 5 weeks :( it really doesn't add up, but I've got no symptoms of a miscarriage

I thought I was 7+5 when I went for my first scan (based on LMP) but baby only measured 6+1 (fortunately with a heartbeat).

I went back for a follow up 2 weeks later and baby measured 8+2 so had grown proportionately.

The dates didn't really add up but I was happy baby was growing then, at my dating scan, she'd caught up by a week which made much more sense dates wise.

I'm now 32 weeks and she's measuring almost exactly on the 50th percentile.

Thank you for sharing your experience @sel2223 and I’m so pleased it worked out for you. It’s interesting that your embryo caught up having been so behind. I think I might believe that could happen if ours had a clear heartbeat, but there was just a flicker.

@AncientandPregnant it caused a fair bit of anxiety at the time as there were only a few days when I could have conceived (LDR) and the dates from the scan were a week out.

The sonographer said it was fairly common in the very early stages and didn't seem concerned at any point, but she did say that a day or 2 earlier (so baby measuring 6 weeks or less) and I may not have seen a heartbeat yet.

Hoping you get a positive outcome too. Good luck.

I'm in a very similar situation so no advice unfortunately. I had a scan due to severe pain at what was supposed to be 8 weeks and they said possibly just 6 weeks, but there was a heart beat.
I have a dating scan on Tuesday, no symptoms of a miscarriage but I am absolutely terrified.
Good Luck x

I have had this twice. First time was a missed miscarriage. The second time, one of my twins was measuring weeks smaller than he should and I was advised that he would probably not develop past 9 weeks. He is currently in his cot.

I've unfortunately had this experience twice and both times I went on to miscarry naturally quite soon after. I'm now 26 weeks pregnant so hopefully third time lucky - this time around I had nhs scans at 7 and 9 weeks which were both measuring in line with expectations. Crossing my fingers that all is ok for you - sorry to have shared a negative experience but need to be honest - I had far too many people telling me 'I'm sure it'll be fine' when I was going through it even though in my heart I felt that things weren't going to work out. Best to give yourself some time to mentally prepare for a negative outcome without giving up hope, it could go either way but I'm crossing my fingers for the best outcome for any of you going through this nervewracking experience.

Just to add to my post, I was 100% clear on my dates as have fertility issues so had been very closely tracking my cycle. If you're not clear on your dates then a positive outcome is far more likely.....

I experienced this exact scenario, with the added certainty that my dates were correct because I had undergone fertility treatment. I continued measuring 2 weeks behind until 10 weeks when I miscarried. I remember searching for hours on the internet for stories of good outcomes, but they all seemed to hinge on dates being incorrect. As painful as it is to face the contrary, I think that false hope can be a bad thing. If you are certain of your dates as it appears you are, and are also experiencing less symptoms than you would expect judging by previous pregnancies, then I think it is probably sensible to prepare yourself for a poor outcome.

I’m so sorry OP, I know how incredibly hard the waiting and wishing and hoping is.

I really appreciate everyone who is coming on this thread to share their experiences and actually it helps to read the negative outcomes because I need to be realistic and google keeps leading me to miracle stories. It’s important to prepare myself for what I know deep down is almost certainly going to happen. I am so sorry others have been through this too.

I did, thought I was 7 + 4 but was measuring 6. Baby did have a strong flickering heartbeat though and I had sex more than once that month. Sorry you are going through this OP, I would expect a stronger heartbeat for your dates.

Scrap that, I read you were 8+6, if 7+6 I think you could be out a few days in which case the embryo would be so tiny a heartbeat could be hard to detect. I really hope things go well for you OP, sorry if I added to your stress.

It’s interesting reading this I forgot about my own experience. My period is like clock work and with my DD I knew the date I ovulated however based on the scan they put back 2 weeks, I never worried about it tbh and just thought ‘they got that wrong’. It was quite common when I googled it. My expected due date moved again at the 20 week scan however I never thought to worry about it then either.

I had this, but unfortunately it didn't end well.

I had no idea about my dates, all I had to go off was a clear blue digital estimation. I had the scan at what I thought was 8 weeks, but was measuring at 5 weeks. I miscarried shortly afterwards.

I hope it goes well for you.

I haven't had this exactly, but I had a scan at 6 weeks due to spotting. My embryo only measured 2.5mm, which looked too small on the little chart the sonographer used. The sonographer said not to worry, as it was very difficult to measure embryos accurately at that stage. My embryo is now a toddler. Fingers crossed for you.

@Cattenberg thank you for sharing your experience. Do you remember whether your embryo had a strong heart beat at that scan?

Hi @AncientandPregnant, there was a flickering heartbeat at 6+1, but I don’t think the sonographer measured the beats per minute. I asked about this, but she didn’t seem to think it was relevant. This was at a (rather run-down) NHS EPAC. I had another scan at 8 weeks (private clinic this time) and they did measure the heart rate then.

Bump in case anyone else has experiences to share.

You could have ovulated earlier or later in your cycle

When I was pregnant with DD I didn't get a positive pregnancy test until my period was 2 weeks late. We booked an early scan due to previous MC,

From my last period i should of been nearly 7 weeks pregnant. I was 4.6 at the scan! I kept saying it must be wrong and explained last period date and they said i must of ovulated later in my cycle

DD is now 5 x

Thanks @wishywashywoppwoo. In my case I only had sex once and got a positive on a pregnancy test 12 days later so I know my dates can’t be out that much. If I am 6 weeks as the scan suggested then I got a positive test before I even conceived!

I’m updating this thread with my outcome as over the last week I’ve searched repeatedly for stories like mine and hated it when I can’t see the outcome.

Scan today still showed no heartbeat although baby had grown 1.5mm this week. No heart beat over three separate scans over 2.5 weeks was enough for them to diagnose miscarriage. I will have a D&C next week.
