I favor parental notificarion for an abortion. The girls paretns won't "kill" them if she tells she is preganant. (At least I would hope not)
I don't know if you've ever known or conversed with a girl who's parents found out that she had an abortion. The parents ended up kicking her out of the house the day she turned 18, and haven't exactly spoken to her since.
Kicking an unruly child out of your home isn't always the wrong thing to do. I've known quite a few people who've done it and it ended up being the best thing for the child.
While the child may have had an abortion, that does not mean they're unruly -- some may be, but I'd bet that many aren't, and would qualify as kids who just made a big mistake. They shouldn't have to get kicked out of their home for it.
See, this is the liberal in me
