Two babies - separate sacs
approx. 10 weeks
This is one of my ultrasound pics at around 10 weeks along. You can clearly see that each baby has their own sac, although they did turn out to be identical twins.
Anyhow, I thought I might as well add my own twin ultrasound images even thought this is my site...lol! And, yes, that's my belly comparison on the Twin Belly Gallery page too.
Enjoy and thanks for your contributions!
