Talk to the OB and let him/her know what you want or don't want. The doctor will let you know what is absolutely necessary and what you can "slide" with. Just always keep in mind that these tests are being done to make sure of the health of your baby.

I would have given anything to be in your shoes. We were never able to have children. I would have personally sawed off a leg without anesthetic if it meant that I could have had a baby.

Congratulations on your upcoming new little one.
