So many young moms here ...

I just don't understand when I see people here who are in their very early 20's and say they have been trying to conceive for multiple years ... How many people here started trying to conceive in their teens and why. I seek to understand.
Edit: thank for all the stories. Like I said, I just wanted to understand the point of view of very young women trying to conceive. I had my daughter at 22 and it was difficult and unplanned which always made me struggle to understand how some people plan for motherhood even younger than I became one. Thanks for not taking offense.
