Mrs T,
Although chlamydia usually shows symptoms early, and it would be unusual for you to carry this without symptoms, it is difficult to say for sure that this did not happen. Here is a link to the CDC website about chlamydia:

You should also talk to your husband about getting tested for chlamydia as well so that he can be treated for this if he has not already done so. If both of you are not treated then the chlamydia will recur.
