If you have had an ultrasound please answer my questions it would be greatly appreciated.

I am giving a presentation and I want to ask some questions to men and women who have had an ultrasound(of any kind not just babies) about your experience. 1.Did you have a good or bad experience when you had your ultrasound? Why? 2. Did the sonographer make you feel comfortable? 3. Do you think the sonographer did a good job of informing you on what they were going to do and answer any questions you asked? 4. How could your exam been improved? Please feel free to share your experiences in detail. Thank you!
