Teen pregnancy in the series

Hello! I’m a super huge fan of the Alice series and I’ve read the whole series. In the series, 2 of Alice’s friends get pregnant but I was wondering, Why didn’t you ever make Alice pregnant while in high school? Was it because you didn’t want to set a bad example for the young ladies reading the series? Why didn’t she lose her virginity in high school?

I’m not going to go back and try to find out which two girls got pregnant in high school–as I remember it was only Pamela among her Alice’s close friends–I have no idea how many other girls might have become pregnant or lost their virginity in high school.   I just didn’t envision this for Alice.   I guess I wanted the first time to be completely unusual and unexpected for Alice, and I really loved writing it when it came time.
