Update: scan today. Still small sac. Embryo still 6 days behind. Measuring 6weeks 5 days but should be 7 weeks 4 days. But heartbeat is now 145. Up from last time. And embryo has grown. It was 0.38cm last week and it’s 0.79cm now. So it could still go either way… gotta have another scan in a week. So scary….

I’m very anxious. From the moment I got my bfp it’s been scary news.. my hcg has risen too slowly and my fertility specialist was pretty worried. He gave me a scan because he was worried that my pregnancy was not progressing. So at 6 weeks 4 days I had a scan and turns out that my sac is small and my embryo is measuring 5 days behind.

So it’s measuring 5 weeks 6 days.

But it has a strong heartbeat of 128beats.

So now I have to have a repeat scan on Tuesday. That’ll be 7 weeks 4 days.

It could go either way I know. Just looking for some positive stories from anyone who had a small sac and slow growing embryo…

The wait is so painful

Hi Eggbabe. I can fully understand your cause for concern. Now you can see why I prefer 7 week scans and not 6! It could just be that your little one is a slow starter and needs to catch up. Fingers crossed that this is the case and your next scan will have mor encouraging news. Thinking of you. Diane

Hi hon, no worries at all, my friend had twins and one of them had no heartbeat And small at first ultrasound but the second one was ok, but on the second ultrasound smaller one catch up and now they both are 2 years.

I had same experience in my ultrasound couple days a go and she told me her story with her twins.

Just relax and enjoy your pregnancy 😊

I can understand this must be a really anxious time for you and waiting for the next scan will feel like forever. Just be kind to yourself. I think the fact there’s a strong heartbeat is a really positive sign. Wishing you all the best for your next scan and ongoing pregnancy xx

Why do they scan so early under IVF? Under normal non IVF pregnancy isn't the first scan not until 12 weeks?

Hi I think it’s bc around 7 weeks you can see a heartbeat. I had a scan so early because my hcg levels were really low and they were worried not a viable pregnancy

I believe it’s to make sure the embryo is growing in the right position and determine if there’s one embryo or two. I think after going through the IVF process most ladies also need that reassurance for their mental health and sanity! I’m waiting for my first scan and losing my mind. The anxiety after ivf is unbelievable. X

I am sorry you are going through this. I hope it turns out OK. 🤗 I went for my 7w scan and my little one was measuring 6w4d with a strong heartbeat. At 12w scan she had caught up and was measuring bang on 12 weeks! 🥰 My FS was not greatly reassuring after the first scan and kept reminding me that even at 7 weeks the miscarriage rate remained at 20%. I think this "reminding" me about miscarriage was tempering my expectations that I was definitely having a baby by preparing me that the worst could still happen. He kept doing this right up until the 14 week scan! 😅 I'm now 21 weeks!

Your FS may not be thinking that anything is specifically wrong! They may just be reminding you how fragile pregnancy is at this early point! I sincerely hope your little one catches up! This is a much more stressful time than the 2ww (at least it was for me) so please be gentle with yourself. Take time to relax, do things that take your mind off it and eat good food!!!! Once morning sickness sets in you'll be glad for the times you ate healthy for the baby! 😊 Good luck!!! Xxx

You sound just like me... I am 7.5 weeks now, and it's been stressful from the start. My first two HCGs were far too low, and I went for my first scan at 7 weeks and was told the embryo was measuring a few days behind and the heartbeat was a little slow (107 bpm, so your heartbeat at 6+4 sounds amazing!)... it's so so stressful. Best of luck x.

I had a tiny bit of pink blood when I wiped yesterday so I’m totally panicked. I hope you have an ok time waiting for 2 weeks. It’s so hard…
