pregnancy

Laura • 28 yrs old. TTC #1. TTC since Nov 2014. never conceived before. just want my own little miracle.
Do people actually get pregnant naturally after 1 1/2 to 2+ years? Without help because I'm starting to believe it's not possible. pregnancy isnt even possible. (This is a simple question, not a forum for you to recommend help. I'm fully aware. I just wanna know if it's even a thing or if a year is just the magical cut off time)
