I’m so very confused - Empty sac then sudden yolk sac appearance!

[Tanzania99]

I hope to goodness someone might be able to help me interpret WTF has happened to me.

We have been TTC baby #4. My 3rd was born Sept 2020 and I was breastfeeding.

Period returned on 20 October, was pretty heavy but nothing too out of the ordinary.

My app suggested fertile days were 30 Oct - 3 Nov. We DTD nearly every day through that time. I didn’t really see any signs of ovulation though.

Then on 14 November I had some EWCM so we DTD again 14 and 15.

On 17 Nov I was “due” my period according to my app, so I tested. An internet cheap strip test showed the faintest of positives. A FRER taken the same day with FMU also showed a good line. Hooray! I was pregnant.

I ended up getting an early scan on 2nd December. I was estimated to be about 6w then based on my positive test. But there was just an empty sac.

I went to a private scan on 9th December as my head was all over the place and I couldn’t cope. Still empty, but bigger.

Today I returned for my official NHS scan, 12 days since the first. There was a yolk sac, but no fetal pole. The sac was also bigger.

I was absolutely shocked to the core. I’m also experiencing a little bit of mild nausea the last few days that comes in waves.

How can this be? What the fuck has happened and if that yolk sac has appeared in the last 5 days is that a good sign? Could I have miscarried and then got pregnant again immediately with no bleed? I have never ever been so confused. Am I justified in having some hope? I honestly thought it would be empty again today. I was all ready to schedule a D&C.

I’m back again on 23rd December so I have my fingers crossed for a fetal pole and heartbeat in 9 days but to get confirmation of a miscarriage on that date might very well kill me.

Please help me work out whether it’s plausible I might be ok.

You are seeing progress so that is a good sign . First thing to develop is the gestational sac . Then the yolk sac then a fetal pole will appear on top of the yolk sac . Did they not explain it to you at your scan?

It could be a blighted ovum? Did they mention that at all? Friend had this recently, everything continued to grow but there was no embryo.

It’s one of those difficult situations where unfortunately only time will tell. Good luck x

With a blighted ovum you don’t usually get a yolk sac

That's pretty normal on very early scans OP. Remember all of these structures are tiny and only forming day by day. They are only visible by ultrasound once they get to a certain size.
Did your ultrasonographer not explain any of it to you? Maybe you could ask for clarification? But it sounds good from what you've written here

It’s just so confusing that my dates could be so wrong though, I should be 8w today but the yolk sac was only just visualised yesterday.

After your latest NHS scan which you take as "8 weeks" ... what was their opinion? They must have spoken with you?

I went for scan on Monday to see empty sac and told 5 weeks, when I thought I was 6 weeks. Now I'm waiting for another next week. However, they did discuss with me after and said "it can go either way atm". However the hope is I just ovulated late that month , and it implanted late. I hope the same is the case for you... and that you are just about 6 weeks rather than 8.

Hi tan what was the outcome of this I am in a very similar situation, hoping for a positive outcome. Thank you. Hope you got good news xx
