<human>: So I'm a 25 year old, generally healthy female (stats: 5'8", 125 lbs, caucasian).

About a year ago I was experiencing near constant nausea that sent me to the doctor's office several times. After ruling out pregnancy, doing lots of blood tests, etc., they finally screened me for STIs and I came back positive for chlamydia. I was treated, retested several months later, all good.

At the time, I asked my doctor if I should be concerned about possible complications related to my future fertility.  I know I got it from my ex, who I hadn't been with in nearly 2 years at that point. My partner at the time of diagnosis was tested after I got a positive test, and he came back negative, plus we used condoms every single time we were together. Furthermore, I know his entire sexual history, and both the women he'd been with were virgins. My ex, on the other hand, cheated on me repeatedly during our relationship, and we never used condoms because I thought we were monogamous. 

So, long story short, I'm 99% sure it was the ex, so I'd had chlamydia nearly 2 years before diagnosis and treatment.

My doctor said that I shouldn't play the "blame game", that I must have gotten it from my current partner who was lying, and that I was fine. She refused to even discuss fertility or any sorts of tests with me. I wouldn't even know what that would consist of.

A year+ later, I'm STI free but it still nags at me. I'm worried about the kind of damage that may have been done. I can go talk to another doctor, but as a currently single woman with no intention of trying to conceive anytime soon, I feel a bit silly about it.  Is this a topic worth pursuing, or should I take my first doctor at her word and get over it?

Can you give me a shortened version of the text?
<bot>: If I think I had an STI for a long period of time before diagnosis and treatment, is it worth trying to find out if it had long-term effects on my reproductive system?
