Quoting Vera-Ellen Firefly:" when i went to my last ultrasound (20wks) is it true that it was my last? i want to see my baby when it gets bigger O.O"
That's normal, Even here, Unless you need another or more for some reason, 2 is generally enough, Have you considered getting an independant (Non doctor referred) scan done? These can vary in cost, Depending on the type of scan.
I am getting a 4D video scan, And 3D stills done at 30weeks, Which is costing us $275 but that's in Australia, I'm not sure what the costs are like where you are, But it might be worth looking into.
