6 weeks 6 days

This is officially my second u/s- but, the first one on my SIRM
calendar.

Twin A measures 7w 0d
Twin B measures 6w 5d (this is the only one he measured at 5w 6d,
and then twin measured 5w 5d so it has grown exactly a week).

Twin B is harder to visualize- is that common? We have to really
maneuver to get a good picture.

Both had heartbeats.

Is it OK for one to be a day behind, and one to be a day ahead- with
a two day difference between them?

He gave me a prescription for phenagren and was surprised that I am
battling hypoglycemia this early- he explained what causes it in
relation to pregnancy, and said its a bit early. But, he said the
twins might make the difference, too.
