Hi InaRelationship,
Latex condoms, when used correctly, are like 97%-99% effective. Lets say the odds of getting Chlamydia are 1 in 10 without a condom (probably a lot less likely but lets pick a very conserative number).
With that said, your odds of getting it with a condom are probably like less than one percent (.0097 percent and even that is a high estimate).
Bottom line:
If I were you, I would not lose any sleep over it as long as you know how to use a condom correctly.
I hope that helps.
