I went for my 21 week ultrasound yesterday. When we got to the part where she was going to tell us the gender, the baby was turned and legs crossed... She went on to say quote " there is a absent of penis and scrotum, so its a girl." My question is should I get trust that? I have had three girls and in all the ultrasounds I have had none of the techs said anything like that, much less were the girls ever hiding. Thanks
