when is the first ultrasound supposed to be?

Stephanie
I was called to set up my first ultrasound and dr.appt for baby and I was told they won't do one until I'm 10 to 11 weeks along I was just wondering when is the average time you get the first one cause I keep hearing different times and I'm irritated? Because I am not getting mine done until I'm already 11 weeks. I'm just annoyed cause this is my second baby and I don't remember having to wait until that long to get in.
