HELP! Ultrasound- Freaking Out!
Sat, 10-10-2009 - 10:50am
Hi there! I desperately am seeking some advice/help/assurance... I am 18 weeks pregnant with twins and just went for an ultrasound on Thursday. This was at the perinatologist's office. Doctor was not there just the technician. Well, yesterday the doctor called me and wants me to go back on Monday because the tech could not locate the humerus bone which is the upper arm bone. Arms on twin

I'm so sorry you're having to wait for results.

I would try not to worry. They measure the humerus and femur bones to measure dates, etc. at this gestation. If the baby was hiding an arm, they want to use those measurements. It's more important in twins because that's one of the ways they check for fetal growth compared to the other fetus. That's how they check for twin discordancies. If they can't see the arm then they just ask for a repeat u/s to get that other measurement. They
