There is only a few words I can say: Only in America
In Germany, a few days ago a female soldier killed her secretly born baby inside the army base. If a soldier can keep a pregnancy secret, anybody can. People don't see, what really is, but what they want to see.
I think that is already the problem - somebody should have noticed the pregnancy. That even the parents did not notice it, is usually a bad sign.
My parents found out everything I did, the more I invested in secrecy, it took only a few weeks longer to find out. My parents did not talk to me when I started smoking secretly with 14. They talked to me when I stopped smoking with 16. :dry:
Also, a pregnancy with 14 is not automatically bad. It is uncommon in our culture, but medically not only possible, actually even physically intended. Some cultures would ask a pregnant 16 year old, why she has not even one child yet.
The problem is just, that like in all other cultures who let their children become adults so early, this requires full work of the children and the new grandparents - and the rest of friends and family. And I strongly doubt that children are considered a family project in our culture now.
Also, I had some months ago seen a young girl, which was unlikely as old as 14, more like 12-13, which was clearly pregnant - you can't gain weight so selectively as woman. Her mother was right aside her, and from the look at her, you clearly can tell, who was responsible for explaining important things to her.
