Anyone else worrying that their early gender scan before 18 weeks is not accurate?

my girl didn't want to show us her lady parts at 20 weeks I can't imagine her wanting to show earlier... I'm a little glad we waited instead of getting a false gender..

My early one was wrong. The tech said at 13 weeks she would bet her career on it being a boy. We've had 4 US's since then...all girl lol.

i got mine gender check at 14 weeks and it was accurate as ever.
