I've also never had the nt scan done before so its a nice surprise!
Thanks I have 3 boys already so I am in for a change this time around :-)
I had 2, one with my 2nd baby and with my 3rd. Both were right. A lot of ppl might say its not very accurate but it all depends on the development of the baby. Some techs can see very clearly what the gender is :-)... Congrats!
