Do her parents know about it yet? That would be the best thing to do, and even though they will be upset they can help her. Is she absolutely sure she's pregnant?
Abortion in my opinion shouldn't be an option and although your friend doesn't want to give her baby up for adoption sometimes that is the best thing to do for the child if you aren't able to give it the life it deserves especially being 15 and not finished your education. Her parents could help her sort out her feelings and what to do about the child.

I agree with tanya 100%, the first thing she needs to do is to tell her mom, she may be hurt or upset, but I guarantee that her mom will be there for her to guide her on the right path.

1. Tell the parents (both sides)
2. See if parents/family (adults) will help
3. Take a parenting coarse
4. Contact doctor (and health unit for advice and prenatal care)
5. Read up on all aspects of pregnancy, ask questions
6. Eat healthy
7. No partying/drinking/smoking/drugs

telling her parents is the most important step at this point. If she has no support and feels unable to support this baby she may have to consider adoption (depending on his families insight as well).

Tell her good luck and stand by her.
