Transvaginal Ultrasound, humane?

So Virginia has a law that requires females to have a Transvaginal Ultrasound before they have an abortion. The doctor then sticks an eight to ten inch wand inside the female to take a look at the baby. With this procedure the female is not required to look at the baby, this part confuses me. If the female does not need to look at the ultrasound picture, why even do it? If a female is raped and wants to get an abortion, why should she have to go through even more stress of getting a foreign object stuck up in her when she has already had to file a police report and asked personal details about the incident? I feel as though this is wrong and Virginia will find problems within this law.
