Why??

Why are there so many women on here who are trying to conceive but are not yet married? A lot of times I'll see women's bios say "Getting married in October, TTC baby #1!" or "Engaged to my best friend, TTC #2!"
Why not wait until you get married AND THEN try to conceive?
This isn't a judgement post, I'm curious. I'm not married and I got pregnant on accident. Why are y'all who are unmarried purposely trying to get pregnant?? What's the hurry?
