Hi, I asked the sex of dc3 yesterday at my scan and the sonographer had a look. I told her my boys wanted a brother and she said I think they are going to be disappointed! She continued the rest of the scan referring to baby as she. At the end she had another look and showed us the bottom, the lack of testicles which is what she said they look for and explained the three lines that indicate a girl ( however I didn't see these).
How accurate do you think identifying the gender is at 20 weeks? Was any one told a girl and then went on have a boy?
