12 week ultrasound to find out gender

I had an ultrasound at 12 weeks and asked my tech if she could tell the gender. She said she was pretty certain it's a girl! So I went to my 18 week scan last week and she confirmed it is, in fact, a girl. A lot of people claim you can not tell gender at that far along. However, I do believe if you have a very good ultrasound tech, they are able to *sometimes* tell. I also had dreams ahead of time that it's a girl. I think there is something about a mother's intuition! But yayyyyy! I'm having a girl!!!!
