Kaiser & Gender- San Diego Area

Karissa
I am a Kaiser patient in the San Diego area. This is our first baby & my husband & I are so excited. We opted to do the genetic testing just because we would like to know to better prepare if something were wrong. I've read a lot about people finding out their babies gender either through blood test or the NT ultra sound. Our doctor didn't ask us if we wanted to find out the gender & didn't tell us the name of the test we were taking. Just that we were doing blood tests during the first & second trimester along with the ultra sound. My question is, is it likely that we may find out our gender? Or is the 20 week anatomy scan probably our best bet? Just curious. Thank you for your input (:
