Anyone find out gender 13.5 weeks by US?

A❤

Hi! I got an elective ultrasound when I was 10 weeks. There the technician said I could come in at 13 weeks if I wanted to find out the gender just don’t come in 13 weeks exactly incase I am measuring earlier. So she recommended atleast 13 weeks and a few days. Anyone else find out the gender by ultrasound that early? I did at 14 weeks with my son so I guess a few days earlier isn’t that crazy.
