Sass they do the 12 week nuchal scan here in Canada (or at least in my city ) as part of routine prenatal care. I get a dating u/s, a 12 week to measure the fluid behind the neck) and a 20 week anatomy. If there are any issues they will repeat them as needed. For example my 20 week scan showed the baby heart was tilted on its axis so not only did they do a fetal echocardiogram but they repeated my anatomy one at 22 weeks lol. Turns out my daughter was just uncooperative. All parts normal. We don't pay for any of that. It's all covered by provincial health insurance. I wish u guys could have that too!
