Teenage pregnancy is okay?

It's not new news that pregnancy is a big deal for teenagers across the world. Television shows that have been running for decades have had a character or two that dealt with this problem. For example "Degrassi's" character Mia has a daughter and it affected her school life. But has teenage pregnancy become such a big problem that there are shows and movies based on pregnancy alone?
Shows like "The Secret Life of an American Teenager" and movies like "The Pregnancy Pact" express the reasons behind teenage pregnancy and the consequences for it. Since all these shows and movies have been coming out, does that mean a lot more teenagers have been getting pregnant? Explaining these situations through media is a great way to make the young teenage mind understand the consequences. What I wonder is, is having shows and movies about teenage pregnancy a warning for teenagers or is it promoting the idea of being pregnant at a young age; saying it's okay?
