Chlamydia and infertility?

Okay so this is kind of long but does anyone know anything about chlamydia?? I know it eventually causes blocked tubes if left untreated and im really scared.. Heres whats going on.

I just had an ex boyfriend call me.. I dated him like 4 years ago? I havent seen him since. But he just called me to tell me he could have possibly given me chlamydia.

Ive been in one relationship since then and ive never had any symptoms bt i also havent been test. I know i should go get tested immediately but if he gave me chlamydia 4 years ago, that means i could have all kinds of problems and it could possibly explain why i cant get pregnant.

My husband and i have been NTNP for the last 3 years and about 5 months ago we started really TTC but been having issues.

Since i have very regular periods and i believe i am ovulating, everything seems to be working fine except im not getting pregnant.. im starting to suspect that my fallopian tubes could be blocked from the chlamydia IF i do have it and have had it for so long... Im angry for just now finding this out.

The last time i was tested for any stds was after i was with that guy and before my husband and i didnt have anything. Could it be possible that i had it but it didnt show up in the screening? Im scared now that i wont be able to have babies and i just feel like ive been robbed of any chances of having children.

Not only that, but now i have to go get tested and if i do end up with chlamydia, i have to tell my husband of 3 years that we both have it and it could be the reason why we arent able to have children!!

Im so upset i just want to cry. Please can anyone chime in on this? Im an emotional wreck right now.
