Here’s the thing.
Her education on birth control and sex ed is limited to what the schools and her parents told her. The Internet is a huge minefield of information but it is also full of misinformation. And her ability to get birth control depends on her parents cooperating by driving her to the clinic, picking up the prescription and so forth.
As for raising the child, her options re extremely limited because she is not old enough to even hold a job. No job, no apartment or ability to feed, clothe and so on for herself, much less an entirely new human being who is ultra dependent on her for survival. So it would be her parents (or foster care) responsibility to step in and take care of the baby.
How can you be so utterly stupid?
