If I've been trying to get pregnant for 9 months is there something wrong with me?

Can chlamydia mess up fertility if not treated I had it twice and now I'm starting to think that's why I'm not getting pregnant 😔 I'm not sure how long I had them but I got treated never developed pid though. I don't have the money to get tubes checked. Doctors told me I have nothing to worry about I just don't know
