Early (not so) reassurance scan

[Cindy974]

Hi everyone, desperately seeking experiences (positive if possible) to stop myself going crazy.

Its abit of a lengthy one, so abit of history….

I had a natural miscarriage on Christmas day when I should have been 7 weeks based on previous period. I had a scan to confirm complete miscarriage on New Years day and negative test.

So I start using ovulation strips to see when I would ovulate again as I stopped bleeding me and DH wanted to try again straight away rather than waiting for a cycle. I got positive opks on 12th and 13th of Jan and then a negative opk on 14th of Jan so I’m assuming I ovulated around then.

I got my first positive test on a FRER (the early ones) on 24th of January. And since then tests have darkened as I expected. I booked an early scan yesterday based on my predicted ovulation which I was expecting to be measuring 7+1. Had an internal scan and there was a gorgeous little blob with a heartbeat, I was so happy and relieved. The scan lady was really positive but when she measured baby I was only measuring 5+6?! Thats the not so reassuring bit.

She did say its so hard this early to get an accurate measurement when baby is so small but surely after having a positive test nearly 4 weeks ago I should be further along?! Im terrified baby is not growing correctly and Im going to have a MMC. Im going out of my mind and dont know what to do? The lady who scanned me didnt seemed worried in this slightest.
The baby measured 4.5mm CRL.
Could my dates be out and baby can suddenly grow and catch up? Has anyone had similar experiences? Is this bad news? I don’t know how to feel, Im so happy with the heartbeat but the dates don't add up.

If you got this far thank you, I hope someone can help me x

Hi Op,

Early scans are notorious for dates being out, you're probably going to find lots of people will come along with stories either way and unfortunately it is one of those things you'll have to wait out as hard as it is.

I had a very similar thing I should of been 8 weeks and they measured baby at 6+4, it wasn't a good outcome for me but I've seen more posts on here where it has been a good outcome.. could you have another scan in around 2 weeks?

Are you able to go for another scan in a week or two OP? Did the person doing your scan suggest the measurements could be at all inaccurate given your conception date is known or offer any advice on why they might not align?
A healthy heartbeat sounds positive 🙂 I hope it all works out!

@ChinChilly sorry to hear the outcome wasn’t good for you. I know it’s the waiting and worrying thats killing me. I could but money is really tight so I’m torn on whether to wait until I have my NHS 12 week scan 🤔

@Poppybloom55 I could book another but money is really tight so Im not sure what to do, wait or get another scan. No but she was rushing and I did cry like a baby before they even started scanning so I think she was trying to be reassuring. She said “this is not a 100% measurement” and told me my NHS dating scan would be more accurate. I know the heartbeat was lovely to see and thank you❤️

Yes, it's perfectly possible the measurements would be inaccurate and slightly off at this stage. HB is good news. You need to do your best to relax now.

I totally get your scanxiety, I had 3 MCs before having my son, two of them were missed miscarriages diagnosed at scans with no previous symptoms and every scan was a nightmare to me, especially some I had on my own in covid.

BUT at this stage it's looking good and keep telling yourself that. Keeping everything crossed for you, deep breaths and put your feet up xx

Also your sonographer is correct, the NHS dating scan will be more accurate because the baby will be bigger then. However, be prepared it might bring your EDD forward or delay it to what you've calculated yourself and that's perfectly normal too. Babies don't always grow precisely in line with our estimated (or confirmed) ovulation date and that's normal xx

Hi OP, it's perfectly normal for dates to be out based on measurements at this stage.
I had a scan at what I thought was 7+2 and measured 6w. She is now 13 months so it doesn't have to be negative.
Wishing you the best of luck

Reading this has sent me into a spin too to be honest. I had a scan at 6 weeks exactly last weds and measure 3.7mm. Sonographer said that was okay for 6 weeks, and heartbeat was present, but she scanned me during previous MMC and knows how terrifies I was - so I’m wondering now if this isn’t okay - given yours said that 4.5mm is less than 6 weeks. Hopefully my lady was correct and that would be reassuring for you too as you’re almost 1mm ahead - if that makes sense x

@PurplePansy05 thank you so much 💕 I’m so sorry to hear of your experiences, it is mental torture and such a difficult thing to experience. I think I’m going to try and hold out for my 12 week scan, I need to register with a midwife too been too scared to at the moment

@WTFUterus thats really reassuring to hear 💕 thank you for your well wishes

@HopingForRainbow2021 Im so sorry that has worried you, I feel like sonographers have there own ways of measuring and dating things. Sorry you went through a MMC how awful, are you going to get rescanned? Sending you all the luck and positivity for your little bean 💕

I had a scan at the EPU at 7+1 in this pregnancy and was measuring "around" 6 weeks, i too had the same anxiety even though I heard the HB. I decided to pay for a private scan last week to check everything was progressing ok at 10+4. That sonographer bumped me forward by 5 days to 11+2 and said I may even be further along as she couldn't get an accurate measurement of baby because of how they were laid. I really wouldn't worry as the babies are so tiny at that stage that they're very difficult to date x

@Cindy974 thank you, wishing all the best for you and your little bean too xx I’m due to go for another scan next weds at 8 weeks. She said she just thought my consultant would like me to have another scan, but I’m not sure why really. I’m not really having any symptoms to speak of either which is also worrying me x

Just wanted to update this thread if anyone came across it as I hate not seeing peoples outcomes. Unfortunately it was not a good outcome for me, I miscarried naturally last night. Absolutely devastated and broken.

So sorry to hear that OP

I'm so sorry x

Thats terrible news, so sorry OP 💐

So sorry op, I wish you the best for the future. Xxx
