Well, of course not, because it's a fictional story; and if she had, it wouldn't have fit the book's plot.
In real life, you never know. My grandmother was wed at 17 to my grandfather after my mother was conceived, and they stayed married until my grandfather's death.
I am currently re-involved with my "first" (I was also her "first"). I was 16, she was 15 at the time. We are now 48 and 47.
Throughout history, all over the world, people have married in their teens. The fact of someone's teenaged status doesn't preclude him or her from loving someone forever...it is no different today.
