How long does it take for azithromycin to clear up chlamydia?

[Meeem]

Last Friday I took azithromycin to clear up a possible case of chlamydia. I say possible because although my test results hadn't came back, I showed possible symptoms and my doctor chose to go ahead and give me the treatment just in case. She also gave me metronidazole to take for a week to clear up any other possible infections.
My question is, I took the azithromycin Friday morning. Tuesday night I had unprotected anal sex. My concern is, if I did in fact have chlamydia, what are the chances I passed it to my partner?
I've heard that azithromycin can clear chlamydia up in two to three days and I've heard it can take up to a week.
At the time I had sex, it had been close to five days. At this point, I don't even have my test results back so hopefully I don't have it to begin with, but I'm just anxious and waiting... so, help?

It can take up to the 7 days to work, so its possible that you might have spread it to your partner, and if your partner has it and hasn't been treated, he/she might have re-infected you.
