I keep posting this in different forums - multiples and then gestational complications and nobody seems to ever have heard of a large yolk sac. I feel like a weirdo now. Surly someone must have experienced this at some point or heard of it. Here was my original posting with all the info:

I just posted this earlier in the twin and multiple sections, but I am mostly concerned about the enlarged yolk sac. I have googled it, which I KNOW I shouldn't have, and it says it is associated with downs! I am so nervous now. The doctor didn't say anything to me about chromosme issues, just that they both believed it wouldn't survive.


I am currently 9 weeks pregnant. At exactly six weeks I had slight spotting. It was so slight that I wasn't even going to inform the doctor, but my husband wanted me to since they explained at our first visit to notify them of any spotting or bleeding. When I called I was suprirsed that they wanted me to go to an ultrasound just in case. When I went that week they found two sacs. The first one was fine. The second was was measuring about a week smaller and they couldn't even tell if it was a twin pregnancy or not since it was too early to see anything. I went back Thursday to check to progress of the second sac and confirmed it is a twin pregnancy. However, the smaller baby is measuring about a little over a week smaller and has a large yolk sac. They said a large yolk sac is a problem and usually means I will miscarry.

They said that I will either absorb the other twin, miscarry the twin or go on to have a twin pregnancy.

Has anyone had this or heard of this before? I have to go and see a specialist in two weeks.

I am just nervous that if I do carry twins the smaller one will have problems as it is obviously not developing correctly. This is my first preganncy, so while I have no idea what is going on and dealing with the regular panic,
I have this.

Hi sorry I haven't heard of this before. Good luck hun xxxxx

Ive never heard of it either hunni but just wanted to say good luck x

Sorry I don't know anything about it but I hope you get some answers soon x

HI didnt want to read & run I have never heard of this. But have heard of vanishing twin syndrome, a friend of a friend had 2 sacs when she was pregnant and was meant to be a 'twin pregnancy' but absorbed it. so now its just a single pregnancy. Dont know if she had a large yolk sac tho .
Wish i could be of more help

Well first thing comes to mind, maybe the other twin was conceived at a later date. I have heard of this happening before.

All in all I hope your little ones will be okay.

Thanks so much for the help. I appreciate your effort! Figures something totally bizarre would happen to me.

good luck hun xx

Hun didn't want to read and run, I don't have any answers I'm sorry, but I hope it all works out for you chick x
