Am i too Young?

Okay im 21 years old...turning 22 soon but i know that doesnt matter. I have a steady job and and AA in Early Childhood Development. I have been accepted into the Bachelors of Arts Program to get my BA and MA in Liberal Studies to become a teacher. Cles would be 2x a week from 5pm-10pm. I am a teacher at an accredited infant care and it pays well, i only work 3days and the teachers there get a discounted rate. My Boyfriend of 6 years and I have lived together for 2 years and just moved into a 2bdroom apt. We both have medical Benifits and Work good but Flexible Hours. Our home is roomy. We have been talking about trying to concieve, but my parents are so against it. We are at a wonderful place in our relationship and lives and really want to marry and have a family, but everyone is telling us we are STILL too young. Is 21-23 Still too young to have kids?
