don't worry, sweetie, at least the yolk sac is measuring right on time!

When is your next u/s? Hoping for wonderful news!!
Just FYI you CAN have a b/o that started out with a yolk sac, that's what the one I m/c'd in Feb was. when I went in at 6w5d (they day they SHOULD have found BOTH babies

), it was measuring a week behind then. By 12w it completely disappeared, leaving an empty sac that had kept growing.
