Its still hard to tell a difference at 12 Weeks, but some us techs are either really good at what they do or good guessers lol hopefully yours is and your baby will cooperate!
They might give you an idea, but baby is only about 6cm approx (2-3 inches) long. So can you imagine how tiny their little *bits* are? Even if they say they think it's one gender or the other I wouldn't by coloured stuff until you have you 20 week scan or have a 3d scan.
Okay! I mean 8 weeks isnt reaalllyy that far away (check at 20 wks) but im just so dang impatient haha. Even if they do tell me, im gonna wait to buy stuff until i get in confirmed.
