Identical twins: anyone have 2 yolk sacs in 1 gestational sac?

somedayMom

And when did they determine if there was/wasn't a membrane between the babies?

 

Thanks!

i had three!

the membrane between two of them was found pretty easily, but the other one wasn't found until 22ish weeks. (but we didn't really look at the optimal time, around 12-14 weeks.)

generally, the number of yolk sacs corresponds to the number of amniotic sacs, so if there are 2 yolk sacs, you're in good shape.

Yes - early on it was said that my twins were in one sack, but had two yolk sacks. Seeing two yolk sacks I, according to what I read, is a positive sign indicating that there is probably a membrane in between. I worried myself sick about the possibility of mono-amniotic twins (no membrane), but was relieved at around 13 weeks when my peri found a membrane between the two.

) Good Luck!

I dont usually post on this board, just lurk after the loss of my twins. I found out at my 11 week appointment that I was having identicals and it was at that appointment that the doctor confirmed had mono-mono twins (no membrane) Doctor thinks that because they didnt have a membrane to separate them they got tangled up and thats the reason they didnt survive.
