I'm sort of on the fence, I don't want to have unnecessary ultrasounds, but wouldn't hesitate to have multiple ultrasounds if my doctor/I felt it was important.
With my first I only had one ultrasound, but this time I had no idea when my last period was, so I did have an early ultrasound. I ended up being pretty close with my due date, but I was only going by when I started feeling I was pregnant, so we obviously wanted to make sure. We ended up finding out we were having twins, so it worked out well to find out a little earlier.
