Test Results and Latency Period

I just found out yesterday that I tested positive for chlamydia.  My swabs were taken on Feb 24.  I had symptoms of chlamydia just before Christmas, so I had tests done Dec 23 and came back negative.  The doc gave me chlamydia and gonorrhea meds just to be safe.  One of them cleared up my problem within a couple days.  The doc explained I must have had non-gonnococcol urethritis (NGU) since that is similar to chlamydia, but does not show up on test.  Now they are coming to me and saying that I have chlamydia NOW...but I have NO SYMPTOMS!  I know that you don't necessarily have to have symptoms, but I'd think that if I did last time, then I would this time.  

I was told that I should medicate again and get re-tested in 6 months.  I asked why so long, and the nurse said that I could test positive for quite a while due to the antibodies in my system.  So...I'm wondering why don't they think that is why I'm testing positive NOW?  I've just contacted everyone I slept with in the past 4 months.  And then I found the one that gave it to me!  Nov 20th was the date.  He tested positive right after having been with me and claimed I gave it to him.  But I don't think he would have tested positive so fast.  I was tested 33 days after being with him...and still negative.  I'm quite sure I got it from him, as there is about a 3-4 week latency period and the time frame works out.  Also, I was with someone in December (before I had symptoms), and he came up with same symptoms and negative test in January.

My questions are:
Can you still test negative after being infected after a whole month?
How long after being treated can you test positive for?
What are the chances my test results are just completely botched?

I'm taking the precautions regardless, and trying to encourage those that I was with to get tested.  Some are saying they were tested and came back negative, so they're fine.  I'm trying to tell them the tests apparently aren't 100%, and if they tested too soon after me, they probably would have tested negative as well.  They won't listen.  The rest think that since they don't have symptoms they are definitely fine!  I'm really frustrated with men right now.  Why won't they accept responsibility??  This is why everyone's walking around with chlamydia in the first place!!!!

Testing is conclusive after 1 week of exposure.  It is symptoms that may not show for up to 4 weeks (if they show at all).  There is also possibility of false results for various reasons.

Please don't put the burden of responsibility completely on your partners.  You also have the responsibility of protecting yourself by making sure you use condoms with all of your partners.  

And it is also women who usually do not show symptoms.  The statistics are about 75% of women and 50% of men.  Big difference.

Thanks for your comments.  Just to clarify...the one that gave it to me ALWAYS wore a condom until that specific time.  Unfortunately I did not notice until immediately after that he had done so (I was on my stomach...he always wears one...just assumed).  Normally once you gain a person's trust, you don't feel you have to check the goods first.  Dating has taught me to NEVER trust men!
