My U/S tech said it's a girl, and we are DELIGHTED. Of course, we would have been just as happy if the verdict been "boy." But now that I have gotten used to the idea of a girl, calling her "she," told people, thought about names, worried about her someday dating, etc., it hits me that I will be very disappointed if the U/S turns out to be wrong. The tech told me she hasn't been wrong yet, but of course it's a possibility. Does anyone know how common it is to get the wrong gender info from an U/S? You always hear anecdotes ("My cousin's sister in law was told she was having a girl...") but how common is it really?
