Bravo for having the patience to wait :-)) We didn't want to know the last time, and it was the most amazing surprise - the best one you could EVER have!
We're going to try and find out this time, just to have the opposite experience. Plus, we already have all boy stuff - it would be nice to know if we're having a girl so we can get some girly items :-) We go for our u/s on Friday - fingers crossed that they'll be able to tell us the gender :-)))
Since you don't want to know what is the gender of the baby... then the only person who know is that tech...
Also depends on how you asked the tech... do you asked the tech it's a boy or girl?
Since you don't want to know.. don't be curious about the gender.... To me I rather to now so i can buy clothes....
Good luck
