Jena, we suspect we're having a boy, based on the angle of the dangle from our 12 wk NT scan u/s pic-see below.
I think the 'nub' readings are pretty accurate at 12 weeks if done by a skilled technician who knows what he/she is looking for. Not 100 percent, of course (which is one reason why a lot of techs won't say anything), but I think most of the predictions over at ingender turn out to be correct if the positioning of the fetus is optimal. Our tech guessed boy based on his nub (at 12 weeks), and she was right! I think mara's did too.
ETA: Here's an interesting example study:
Efrat et. al. “Fetal gender assignment by first-trimester ultrasound.” Ultrasound in Obstetrics and Gynecology. 2006.
* Study included 656 participants ranging from 12-14 weeks gestation
* Gender was determined in 93% of participants (7% inconclusive rate)
* At 12 weeks, 99% of male gender predictions were correct, and 91% of female predictions were correct
* At 14 weeks, 100% of both male and female predictions were correct
