I'm sorry to hear what you are going through, and my prayers are with you.
As for whether or not anything changes, no. If you were raped, it was still rape, even if it caused a pregnancy. Only an insensitive @ss would say that it is your fault that you got pregnant when you were raped.
Have you spoken to a rape crisis center in your area? The hospital that did the rape kit, or the police who took the report should be able to direct you to somewhere. If you did not report the man who raped you, you should still be able to call your local police or hospital or House of Ruth to seek help.
I'm a social worker, and while it isn't my primary clientel, I have worked with rape victims in the past.
