<human>: We have been together for 4 years.

I know, we are super young, but I just need some advice from adults. I don't know how to talk to my parents about this. My girlfriend has been on the pill the entire duration of our relationship. I usually wear a condom, unless I'm out. I think we've only done it without a condom maybe 4 or 5 times in our entire relationship. Her pills work really well with her and she's a perfect user.

This month was a little weird for her. She felt fine until the third week, and then she got crampy, and then her period came 4 days early. She kept taking the pill, but the cramps were horrible for her and she missed Thursday and Friday of school. On Friday, she went to her doctor to figure out what happened and the doctor found out she had been a 3 weeks pregnant, but had miscarried the baby due to continual use of birth control and mostly just living unaware of her pregnancy.

Neither of us wanted a child, so we were both in major shock to have known we had created a baby. And then we felt sad because she lost it. For the most part, I've accepted it. But I know my girlfriend feels bad about the whole thing. She says she probably wouldn't have kept the baby, but she felt bad because she killed it with her pills. She realizes it wasn't exactly a living, breathing baby, but she feels sick knowing she killed a prospective life.

I want to help her through this. What are some good things I can say to her and do for her?

Can you provide a brief rundown of the text in within 3 sentences?
