I had my appt yesterday to get my 20 week scan even though i am 21 weeks. The ultrasound tech said girl is it possible though that she could be wrong? She told me that by now its very obvious to tell if the baby is a boy or girl. And she was certain i asked her to check all angles to make sure she said girl every time. Now she also told me that its mostly in the fathers dna that chooses the sex if thats true then we have a baby girl on the way, he has 4 sisters and is the only boy out of 5 kids. I was disappointed at first but now thinking about it i couldnt be happier. Im just wondering if its possible to get the gender wrong???
