Have you been tested for ALL STDs and STIs? If not, I would go about doing so immediately.
From what I understand, chlamydia itself does not cause fertility problems. But if it is left untreated it can lead to PID (Pelvic Inflammatory Disease.) PID can cause blocked fallopian tubes which can make it difficult or impossible to conceive.
If you do not have any other STD's or STI's you should be all right.
