  • Oh yay! I can bounce my newly acquired twin knowledge off of someone!

    At the ultrasound I had at 6 1/2 weeks, there were definitely 2 yolks sacs. From what I've read so far, the medical research all indicates that the number of yolk sacs should correlate with the number of amniotic sacs. I did read one personal story of a woman who had 2 confirmed yolk sacs at an early u/s, but still ended up with mono-mono twins although her doctors could not explain how that happened. So...I'm really feeling good about the chances of these twins NOT being monoamniotic since from what I've read it would be extremely rare to have it end up that way.

    Have you had any specific experience with the yolk sac correlation? I found the research articles that talk about it, but always like to hear real life experience too.

    My OB is all freaked out that these are monoamniotic, but he also tends to be a rather paranoid guy, and either isn't familiar enough with this specific stuff to know of the yolk sac correlations or maybe he didn't pay attention to the picture or report from the ultrasound technician showing them??? Or maybe he has seen 2 yolks sacs still end up monoamniotic??

    Any thoughts?

  • i've not had that much experience with mono-mono amniotic twins, however, i have heard and read that you are completely correct about the yolk sacs correlating with the number of sacs.... i would try to hold out until your ultrasound to be completely sure however, i feel pretty good you've got two sacs.... because if you think about the purpose of the yolk sacs... it is to feed the baby in the first few weeks.... so it would only make sense to me that their will be two sacs.... sharing one placenta is not uncommon at all.... actually i don't know that i've saw twins yet that didn't share a placenta... when is your next ultrasound?

    we actually have a girl pregnant now on a different floor with mono mono twins, she has other complications though.... so i'll dig up some research!
