I always knew I wanted to be a mom — even in my '20s when I was a wild and crazy gal in New York City. I had one friend who swore off any notion of motherhood during our high school years and then 15 years later went through intensive fertility treatments to become pregnant. Life can throw people for a loop and what was once a far fetched idea becomes an obsession.

Cameron Diaz, 37, recently revealed her lack of plans in an interview with Parade. She said:

I'm not somebody who is going to declare either way if I'm absolutely going to or I'm absolutely not going to have children. I have no idea... I'm still young. I have an unbelievable life. In some ways, I have the life that I have because I don't have children.... I don't think it's a compromise to have children. Everything I'm bringing into my life right now isn't geared toward that. It might be one day.

Many women feel like that and then their biological clock ticks and they start yearning for youngsters. What happened in your case?
