ultrasound tech allowed to tell you about twins?

Ligia Elena

i know legally ultrasound techs aren't supposed to tell you anything but are they allowed to tell you if you have twins? i had my ultrasound yesterday and after she finished the abdominal, she stepped out for me to half undress for the transvaginal. she happened to leave a perfect pic on the screen of 2 black sacs with a thin vertical line down the middle and 2 little blobs at the bottom of each sac. this pic is off goggle because i didn't get any printouts, but this is EXACTLY what the screen showed except the middle line was thinner. when i asked her if there was 1 baby she laughed and said yes. I'm nervous now that either she had a nervous reaction and lied because she shouldn't say anything or that i have a singleton that isn't growing right.
