I am by no means an expert on pregnancy, let alone teen pregnancy, so I could be completely wrong in my uneducated assumption. That said, I have always been under the impression that teenage pregnancy rates drop when contraception is taught in school, not when you turn 25. I’d hate to be one of the few 26 year old teens that succumb to teen pregnancy, jesus christ that would be the worst.
Speaking of pregnancy, my 24 year old cousin is pregnant with her first child, which obviously makes her a pregnant teen. However this was published in 1999, so maybe she’s just pregnant and is not in fact a pregnant teen… That Y2K really changed everything.
