please help?!?!

About a month ago I was in a TRAGIC incident . I was raped and now found out I am almost 6 weeks pregnant . My family does not believe in abortions. If I were to get an abortion they would never speak to me. I would be disowned . I am only 17 but I turn 18 December 21st. My parents my family do not care that I was raped. I cannot live with this . It is tooo much to carry on my plate. I was raped , I'm trying to stay focused in med school and trying to please them . If I were to get an abortion behind their backs when I turn 18 would they get mail from my insurance saying I did that? Will they ever know? And can I just act like it was a miscarriage ?
