Good luck tomorrow Ellie- one more sleep..... WOOOT!

Like everyone else has said they check and measure everything. They count fingers and toes, measure bone lengths, head diameter, stomach diameter, look at spine, look at the facial structures, check the chambers of the heart, check the ventricles of the brain, have a look at the kidneys and bladder, liver, stomach, your placenta and the umbilical cord. the list could go on. Basically they check EVERYTHING! Morphology scan generally takes alot longer than the 12 week scan. But do ask loads of questions, especially if you don't understand something or are worried.
Can't wait to hear how it goes. xx
