Please answer! i'm curious....!?

I think a pretty good number of them are teenagers. Teens with little information, weak support systems and not enough life experience to make sound decisions on their own. I'd be willing to bet that they fit into textbook adolescent thinking about and pregnancy... "It won't happen to me." Then it does and their world is shaken. They get catapulted into an adult life and don't know how to function in it.
