Thus, I take it that you define pregnancy at the age of 17 in modern society
as "irresponsibility". Yep. (Statement corrected to re-insert the relevant context, in such a way as to foreclose irrelevant observations about the days when people often married at 15 and died at 40.)
Physiologically a woman is in better condition to have a baby at 17 than at 30 or even 25. As I said before, I bet you harumph a lot.
