Measuring behind at early scan

[mowglik]

I just had my first scan at 6w5 (by my LMP), however the sonographer dated me at approx 5w with a 5.6mm gestational sac. No other structures seen.

Has anyone else experience of measuring behind and things turning out ok? I had a miscarriage two months ago where the sac measured 4w and never progressed beyond that. I’m afraid it’s going to be a repeat of that

I’m sorry this is causing you so much worry and for your earlier losses. Did you track your cycle and know when you ovulated?

I had exactly the same - early scan around 8 weeks and was told I was under 7 weeks. I'm now 38 weeks pregnant, and I think my dates have moved around a little.

I also had a previous MMC so was very nervous about it, but try not to fret at this stage. Bear in mind that you may have ovulated later than you thought AND the scan is so blurred and tiny at that stage that it must be pretty impossible to get a perfectly accurate measurement. I think it's quite common at that stage to not be able to see structures too? I waited until 8 weeks to have a scan as this is when there should be a heartbeat and they can tell more about what's happening, so maybe wait until then if you decide to go for a follow up scan, or for future reference. Congratulations and good luck xx

My scan at 8 weeks told me I was 7, I knew this wasn't correct, and early scans aren't particularly accurate so I stuck with the dates I thought to be right until my NHS 12 week scan and they put me at exactly what I had first thought

Slightly different situation - I had a scan at (by my calculations) 6+1. They didn’t measure anything (that they told me about, anyway); just checked the baby was in the right place and told me there was only one.

At my 12-week scan, they changed my dates so baby was conceived three days before I ovulated. I can only conclude either that these scans are not 100% accurate, or that it implanted earlier than expected and so got a head start. Perhaps you ovulated later than you thought (perhaps I ovulated earlier than I thought!), and baby implanted later than usual?

Thank you christmas I did an OPK and think I caught the tail end of the surge as the OPK was negative the next day. It’s always possible I ovulated later but going by my pregnancy test date I should still be a minimum of almost 6 weeks.

I thought I was going at a reasonable time as my past IVF viability scans have always been at 7 weeks so I was sure I would get a definitive answer.

They have me back in 3 weeks so fingers crossed. The two week delay in devt just makes me feel like something’s wrong though

I don't want to give you any false hope, but....

I had a scan at 6 weeks (going by LMP) and we saw a 4mm sac and was told there was no fetal pole seen and that we'd miscarry, all in outrageously unsympathetic terms. It was said that there was no possibility the pregnancy was viable and to have a medically managed miscarriage (where you take a tablet to induce the miscarriage).

2 weeks after this I still had my HCG levels going up, baby was bigger, had a clear heartbeat and was still going strong. We came very very close to accidentally aborting a healthy pregnancy because of wrong information. At the 12 week scan, my dates were changed to being a week earlier because the baby was a little small, but was fine! Apparently I just probably conceived late in my cycle.

I'm now 35 weeks and baby is still cooking happily. I wish you the best of luck and hope that this goes okay for you. The photo is the scan at 6 weeks where we were told we'd miscarry, I don't know if you wanted to compare it to your scan?

And because my brain hasn't worked well this morning, I forgot to say we refused the medical management, thankfully, as I wouldn't still be pregnant if we had gone for it.

At this stage the measurements are so tiny a fraction of a mm makes a huge difference and all sorts of factors can throw a measurement off by such a tiny amount.

I know saying try not to worry is like asking you hold back the tide, but try and hold onto your sanity until the next scan.

For what it’s worth we measured a day ahead at 8 weeks, ivf baby so very sure on dates. It’s not an exact science.

I am shocked that you were offered medical management. At our trust you have to have two scans two weeks apart before they will over any treatment. National guidelines are that anything under 7mm (when you would expect a strong heart beat) is inconclusive and needs a rescan.

@Jackshouse

It was the consultants decision and he suggested it, and was the one who told us we would "definitely miscarry, this pregnancy won't continue". Apparently he has quite the reputation of not being very good yet still works at our hospital without any sign of that stopping, we walked past him yesterday. He also prescribed me morphine for when I started to miscarry naturally. I was offered a rescan in 1 week by the head midwife, but the consultant said to cancel it as is miscarry anyway. It was only when she called me after two weeks and nothing had happened pregnancy loss-wise that she booked me in for another scan with a different consultant.

That is awful TheOrangeOwl. Would you feel up to making a complaint?

I have had 4 pregnancies, two of which ended in miscarriage and the current one is early with twins and one twin looks like it won’t continue at a private scan. I have been scanned at 2 different hospitals and privately and they are always a very carefully to say they can’t give a definitive answer.

I'm honestly not sure if I could cope with it, if that makes sense?

I understand, I really do. This is my fourth pregnancy but first that made it and we had already had so much loss we just accepted it until we were told at 8 weeks that everything was okay. I did think that, but as I was having the scan, I asked him directly "what is the chance of this pregnancy continuing?" because I am one of those irritating people who need direct answers, and his response was "absolutely none", the midwife said 1% but I think she only said it to be kind, she was the only person who didn't react badly to me crying and was nice. It feels like such a long time ago now, but was 29 weeks ago and this baby is still there, still growing and I'm almost at the end of this pregnancy now.

I wish you every bit of luck and hope there is with your twins, please reply back on this thread if you wish to about how it goes. Early pregnancy is so very hard, and I feel like a lot of people think the hard part is conceiving, but for people such as ourselves, it's carrying that's the hard part

orangeowl I’m shocked to hear that, the consultant was negligent to not offer you a further scan. They always do at my local epu, esp when the sac is still small and still possibility of continuing growth

jackshouse good luck with your pregnancy, sorry to hear that one of your twins may not make it

I’m having period pains which I haven’t had til now and some light bleeding so may be the beginning of a miscarriage it’s funny how it always seems to happen after a scan, it’s like the body needs to know what’s happening before it lets go

Will update, still holding out hope as always

I completely understand both the not having the energy to complain and wanting a definite answer.

I’m happy this time to except that it does not matter what the % is for these two as I know I could be in the 99% or the 1%. I’m counting the days down until my second scan.

I had an early scan today and I should have been 6 weeks exactly as I ovulated exactly 4 weeks ago but I was told I measured 5weeks 1day. They saw a sac and yolk and said it was a good sign but confused as I am definitely more than 5 weeks 1 day as I was tracking ovulation and had a blood test 5 days later which confirmed ovulation and my progesterone level was quite high. I’m being rescanned in 12 days so we will see.
Sorry to hear about the bleeding, I really hope it’s nothing bad.
Are they going to rescan you?

I had scan at 6 weeks and sure they measured me at 2.4mm and put me at 5 plus 3. They did pick up a heartbeat. I have another scan tomorrow at what I think is my original 8w2d by my lmp. I Will let you know tomorrow if I have caught up at all to what my expected dates were. Like you I know when my surge was, I tracked my temperature so I'm pretty sure I'm accurate! I think I read somewhere that accurate dating is between 7 and 12 weeks?

Hi charlyn and mrs. I have a rescan booked for 3 weeks time but I started bleeding properly today, and am having quite bad cramps and back pain, so I think it’s the beginning of a miscarriage. I’ll probably go to the scan in 3 weeks to make sure it’s all cleared out. I’m really sad, second miscarriage in 3 months. Hoping next year is my year!

Good luck with your scans, I really hope you both get good news!

I know this really isnt what you're asking for, but I went for an early scan and turned out I was almost 2 weeks further along than I thought. It's not unreasonable to think that it works both ways! Doctors are people too, and sometimes people can be wrong! Or there could have been little gremlins in the machine! I'm sure everything will be fine x

Sorry to hear that @mowglik but have my fingers crossed for you xxx

Thank you mrs, it was all over yesterday, felt quite bad period pains and back pains like pre Labour and I think I passed the sac, it was fine after that. Not much bleeding, not even as heavy as a period tbh

Hoping 2019 is a better year for us, good luck to everyone else in a similar situation

Very sorry, I didn't see the last few posts XX

@mowglik I'm so so sorry, and wish I could hold your hand. I really hope that you get lucky soon and have your rainbow baby.

I real sorry.
