I have been looking on this board today because I had my first ultrasound and I saw 2 sacs, both with a yolk sack!!! The nurse said one measures 5w4d and the other 5w. This concerns me a bit. I asked her if one had stopped growing possibly and she said that could happen, but it could also be behind the other one further away in the uterus or a late implanter. I am praying that both babies continue to grow and I get to stay for the long run!

Congrats on the u/s! When I saw your intro/siggy on PA35, I figured I might see you over here, too.
My girls always measured 2-3 days apart, and I have an IRL friend whose b/g twins always measured a week apart and they are healthy 12 yr olds now.
