Please help! Measuring behind…

[Ruixue358]

Hi! Really looking for some advice and experiences please…

I had my early reassurance scan on 25 April and I was measuring 5wk4 days, but according to my LMP it should be 6wk3 days. They could only see a gestational sac - no yolk sac or anything else. Im worried that the timeline doesn’t add up…

11 march LMP (period ended 16 March)
19 march DTD
8 April positive test

We only DTD once in March, only a few days after my period ended so i would have ovulated earlier than normal. The sonographer asked if i had a ‘normal’ 28 day cycle and i said yes, its usually 27/28 days, definitely not longer.

So what does this mean ☹️ is it likely a blighted ovum? Or will i have ovulated around 25 March and been lucky to have fallen pregnant as we DTD so early after my period ended? They could also see that i had a slight bleed on the ultrasound (i have not had any bleeding or spotting) and she said it could be implantation bleed (which seems VERY late given i absolutely conceived 19 march!). I just don’t know what to think. The sonographer didn’t seemed worried at all and advised me to come back in 2 weeks, which i will but the wait is torture!

Would love to hear anyones thoughts or experiences, good and bad! Thabk you 🩵

@Ruixue358 you can get pregnant from dtd up to 5 days before ovulation so 24/25 for ovulation is certainly possible, then implantation can take up to 12 days. Furthermore, remember that scans aren't an exact science. A measurement that is out by a tiny fraction could make a difference to the gestation you're told at that point.

On a separate note, I had a scan at 7+2 and measured 6+2. Currently almost 25wks. Stayed on the earlier dates through numerous scans (due to previous losses) - so I must also have ovulated/implanted late.

I'm sorry that this has caused you anxiety but honestly it's so easy to drive yourself mad and agonise over every little thing. For now, you've no reason to fear the worst. The sonographer was happy and seemed to think all was within the bounds of reasonable - you've no reason to doubt them at this stage. And they usually do indicate if there is a reason to be a bit concerned (not sure if this is the same with private scans - was yours EPU?) So, deep breaths and hopefully you will get reassurance at your next scan 💗

I've always measured behind.
1st was an IVF pregnancy so I know to the second and baby still measured behind.
2nd, almost a week behind and she's currently fast asleep.

You don't know when the egg implants.

The baby is so tiny, literally tiny that measurements are harder to get. The slightest movement and it's off.

Hi,

I too am measuring behind. I attended my local maternity after being referred by GP due to extreme cramping. At the time, by my dates I would have been 6 weeks and 1 day. After bloods, they did an ultrasound and told me that they could see a sac but no poles/growth inside. DEVASTATING. Told me go home and due to the cramps I’ve more than likely had a MMC & I’d start bleeding soon, if not come back within a week. The longest most horrendous week of my life passed, no bleed. On rescan they found a pole & a heartbeat. They told me my dates were incorrect. I followed everything to a tee. I showed them on my phone photos of my ovulation sticks with the dates on them, when I got my period and the dates we were TTC. I knew my dates weren’t wrong but they are saying that I must have had a weird cycle ( I didn’t) anyway, I’m 8 weeks this Tuesday and have another scan. Alls going well Barr the nausea and fatigue.

fingers crossed for you & I do hope that dates are incorrect (even if you like me think they aren’t!)

Thanks everyone. It turned out to be a miscarriage/anembryonic pregnancy. Heartbroken 🥺

I’m so so so sorry to hear this. With your permission I will light a candle for you all. If you need to talk please reach out. Thinking of you xxx lots of love

@Ruixue358 so very sorry to hear this. It's a completely heartbreaking thing to go through. I hope you have lots of love and support around you and that your little rainbow will be along soon (when you're ready)🙏🏼🌈 For a note of hope - this time last year I was in the depths of grief after a MMC - this year, I've just entered third trimester with my little rainbow boy. Don't give up hope 💗
