At my 12 week ultrasound the nt measured 3.9mm ... what does that mean?

You need more tests: This test is a screening test done during pregnancy. A value higher than 3.5mm indicates that further tests, such as amniocentesis or cvs, could be useful to be sure that the baby doesn't have down syndrome.
