First trimester maternal/fetal sono


Ok so I am getting a first trimester sonogram right when I'm 12 weeks 3 days. But it's at Maternal/Fetal which is where they do like the anatomy scan and all that ect lime the good ultrasounds (Not anatomy scan yet though) my question is, Did anyone find out there twins genders that early? With my son I found out at 14 weeks through an external source. Just wanted to see if anyone personally has instead of googling.
