can't get pregnant?

Does anyone ever feel like they are running out of time? Before anyone judges everyone has their own opinions and this is mine however I'm curious of others. I'm 22 and I live in a small country town where everyone gets married and has kids young. I'm not like most girls my age i want to have kids and a family younger then later. Just like in my town literally everyone my age has a family. Even people who never wanted kids end up getting them when like for me I want a baby so bad. I'm jealous of everyone who has children. I could even care less about a significant other but I want a baby more then anything it is my dream. I do have some health problems and I feel like that's what bothers me the most is thinking I won't ever be able to be pregnant. My ex and I tried and tried all the time and never got my pregnant. My boyfriend now and I aren't trying however not protecting and I would think it would of happened so I'm scared it is never going to happen for me. I was checked for PCOS and test after test is negative. I hate getting jealous of everyone and wishing it was my time. Sorry for the rant.
