Self-induced abortion

I have a friend who ended her pregnancy in her house. I thought she probably took the pill, but she just told me that she did it with a coat hanger and acts as if it's not a big deal? I'm so worried and confused because I feel like she should get herself checked out, but she's not being herself lately and acts like she doesn't care when she talks about it. She obviously seems like she's going through a really rough time and doesn't want to open up to anyone, and I'm starting to wonder if she was raped or something? A while ago she told me that the baby's father had to move to another state because of his job. I just never heard of anyone going to the extent of terminating their pregnancy with a wire coat hanger. Would you be worried??? Is it normal for someone to self-induce and abortion with a hanger? To me it sounds like a desperate measure.
