Late on kids

I’ll be 24 next year and I’m realizing damn I don’t have any kids I definitely want two kids... I’m not married neither my desire is to be married first but what if I don’t get married until my 30’s 😢 that’s one of my biggest fears. I want a family i look around and see my peers and it’s more motivation for me. Not competition but motivation. And is it true the older you get the more complications you have? I don’t wanna be too old to give birth. Honestly I’m stressed because i feel so behind on life about to be 24 and i feel like I haven’t experienced alot. Still living home 🤦🏽‍♀️
