Gender at 12.5 weeks!!!

Kaylin
Hey all! So I got asked to come be a "Guinea pig" for an ultrasound for a field trip for the ultra sound techs daughters class. 
With my last daughter my tech was able to tell me the gender around 13 weeks! I'm wondering if anyone has found out the gender at 12.5 weeks and been right? I know it's early, but just curious to see who found out! I'll be 12.5 weeks at this ultrasound!!! Would love to know but not holding my breath ;)
