Ok so we went in today and they did another ultrasound. I asked my OB if she could tell what the baby's gender is. The baby is measuring a week bigger, and she was able to look between the legs. I saw the three little lines that I saw with my daughter, and my doctor said if she had to guess she would say it's a girl. Anyone know how accurate it is at 15 weeks? We have the big anatomy ultrasound nov 4th, and will definitely know then. Just wondering what you ladies think.
