It is actually better to do NT NB scan before 14weeks...but you may still get it done...after this also get a triple marker test done to see if any chromosomal abnormality... connect with me online for further query...all the best

NT NB scan has to be done ideally between 11 to 13 weeks of pregnancy ...
after that chances of false negative and false positive results increase drastically...
so if you have missed it now it is advisable for you to get done ultrasound level 2 at 18 weeks

Hi,
You can go ahead with scanning , however it will not be possible to send a Double marker test. As the last date is 13.6 weeks. Ultrasound findings may differ slightly with the dates . The option with you now is to wait till 16 weeks and then send a quadruple marker.
