Yep my first ultrasounds you can clearly tell their in separate sacs but now im 6 months + and babies are literally touching, heads side by side.....the sac is very thin, basically just a thin mucus

Oh Ok, that makes sense. My first couple were really clear as well :)

Agree with PP. As they get bigger the membrane becomes really hard to see. My first couple of ultrasounds were very clearly separate, but then it just became a jumble as time went on. When you have an actual medical scan like for NT/anatomy/growth they try to find the membrane and save a shot of it.

Oh ok, interesting. In some of the pictures the membrane was to the left side and the babies on the right. I kind of figured it was maybe the angle or something. We never saw them clearly in their own sac. Anyway, just thought I was interesting. Thanks for sharing :) and thanks for the congrats! We are so thrilled :)

With my twins sometimes we can’t see the membrane that separates them so it makes it look like they are together ? congrats btw!
