Will I be able to get pregnant?

Me and my fiancé are family planning and January is when we want to start trying 😁

Although I’m nervous because I had chlamydia before🤦🏼‍♀️ and I had it for 3 weeks before I got it treated (I did math I wasn’t sitting around with it waiting to get treated). I never had PID and I was wondering if that would still make it hard to have children. I know it can cause infertility from scarring but not sure if 3 weeks was enough time to do that damage. Anybody have any feedback, knowledge or personal experience?
