A thought on "teen pregnancy"
Teen pregnancy isn't in itself terrible. For most of history, women were "teens" or close enough by our standards when they had their first children -- because most people in history married at an age we consider young.
But pregnancy out of wedlock at any age is a tragedy and is devastating for the child.
Very often, we look at the issue only from the point of view of the mother. We hardly ever consider what not having a father bound to the mother in holy matrimony means to a child.
A lot of harm has been done by trying to normalize unwed pregnancy and by tying it to the age of the mother instead of her marital status.
(Today in the US, the average age for marriage is 30, which is a tragedy for society as a norm -- of course any individual woman may have reasons for it.)
I recommend watching the movie The Well-Digger's Daughter (2011) for some insight into this truth. It's a beautiful film on a cinematic and symbolic level (not everything in it is meant to be taken as a literal or even psychological fact).
