7w 4d with small gestational sac, large yolk sac, good heart rate

[QueenAngst]

I had a bleed exactly one week again so went to my EPU. They put me at 5w5d and found a heartbeat. They also found a small sub-chorionic hematoma, which is causing the bleeding. They weren't worried about the SCH and told me to relax. But then the sonographer said the gestational sac looked small in proportion to the length of the embryo. There is only 5mm difference between the sac and the embryo, which is bad. Dr Google told me that 80% of small gestational sac pregnancies end in miscarriage.

I went to another EPU today - exactly one week after the last scan. I'm now measuring 7w4d. (2 weeks growth in 1 week?!) But there is now only a 3mm difference between the embryo and the sac. Also, the yolk sac is 6.3mm, which Dr Google tells me indicated a genetic abnormality and is associated with miscarrige.

I just feel like I'm waiting to loose this baby.

I'm exhausted, anxious and don't know how I'm going to cope. I miscarried last year too. I'm so tired.

Has anyone got any experience of this?

Firstly, I am so sorry you are going through this stress at the moment and upset.

What did the EPU say about the sizing today?

I think that 2 weeks growth in a week sounds good, but I am no expert.

If Dr Google says you have an 80% chance of loss, Dr Mumsnet says you still have a chance of it sticking

Thank you number3.
The problem is that although the baby grew by two weeks, its sac didn't grow at the same rate. If it outgrows the sac, miscarrige is inevitable. They didn't mention anything about the yolk sac...stupidly I found that out all on my own! I looked at lots of studies of yolk size. I regret it now!

Did they say they were concerned or for you to come back in a week or two? x

They didn't say they were concerned, but I have over researched and have found studies that say the outcome of a small sac Is usually miscarrige. I realise I should chill out on the research! I'm a terrible worrier.

Me too, but worrying is probably more dangerous than ignoring Dr Google xx

I had a scan at 7 + 4 and measured at 7 weeks. I went back a week later and measured at 8 + 3 but with a small sack. This was with the IVF clinic and they were happy to sign me off.

I'm 12 weeks today and waiting for my scan on the 19th.

I'm hoping all will be ok, but I've had nothing to indicate that anything is wrong.

pipbin from my oh so extensive research (!) it seems that small for date sacs are more common on IVF pregnancies and aren't a cause for concern. I really don't know why they cause concern in non-IVF pregnancies, but that's what the literature seems to indicate. Good luck.

I am curious to know how this worked out? I was told I have large yolk sac 10mm to be precise which is very poor prognosis although baby measured correct for dates at 8week1day and had strong heartbeat. I'm struggling to find even one outcome of a live baby after this sort of scan outcome. Anyone?

I don't know whether the OP is still around user but I searched her posts for you and see that she sadly suffered a second tri loss.
I hope things work out for you
