I can guarantee that you are not the only person who will have had that kind of ultrasound at that office and had trust issues. If you find that the person doing the ultrasound (you can request that it be a woman) is not sensitive to your feelings and won't discuss this issue with you, leave. Then tell your doctor. The person you were speaking with might have been a receptionist. There are good ones and bad ones, but she is not a person you need to concern yourself with. Another way to look at it is that if there is something seriously wrong, you don't want your trust issues to hobble your need for diagnosis and treatment. It's important to find out what's causing that pain.
