They check for downs and Edward etc at this scan if your wanting the tests. They check for all limbs being there too I think and to see how many baby’s are actually there as well as the what everyone else has said x

Check due date,baby’s heartbeat, measurements for downs ect and take bloods

thay will also confirm your due date hunni xxx

Check heart beat and that baby is growing properly. Can’t remember if it’s the 12 or 20 week scam they ask permission to check for Down syndrome too
