I think at that point it's just an educated guess, genitalia aren't even developed yet, so they're basing it on what HAS developed, which varies ever so slightly but is very very hard for even an experienced technician or doctor to distinguish. I've never heard of anyone finding out the gender at 12 weeks via ultrasound.
However, there ARE blood tests now that can be taken as early as 12 weeks which can tell you if the baby is definitely a boy, or most likely a girl (based on Y chromosomes in the fetal DNA in the mother's blood). I believe they JUST started allowing doctors to tell patients gender as a result of this blood test (actually a finger stick) - I can't remember which test it is, either the nuchal or MaterniT21. I'm not sure if it's available outside the US for gender, either.Lillian Elizabeth 6.16.13
