where are my mid-20s moms?

Hands up "millennial" moms; I felt like everyone in my child birth class was mid thirties AT LEAST. I KNOW 26 isn't crazy young to have a baby and is actually very close to national average, but why does everyone I see pregnant look so much older? Anyone else feel this? 
Edit: sorry to the mid-30s moms who are also millennials... kinda figured the topic title would take care of that question... 😜
