Unprotected sex with prostitute, please help with tests

[superdude8701]

I had unprotected sex on 12th January 2015 with a sex worker in Thailand. I was extremely drunk and this is no excuse but not a day goes by that I regret this action.

After this encounter, I have had the following tests taken :

At 2 weeks
------------------
Urine culture test : Negative
VDRL : Negative

At 3 weeks
-----------------
- HIV P24 ANTIGEN + HIV ANTIBODIES : Negative

At 15 weeks (3.5 months)
----------------------------------------
- CHLAMYDIA TRACHOMATIS IgG ANTIBODY, SERUM @ (EIA) : Negative
- VDRL (RPR), SERUM (Slide flocculation) : Negative
- HERPES SIMPLEX VIRUS (HSV) 1 + 2 IgM, SERUM (CLIA) : Negative
- HERPES SIMPLEX VIRUS (HSV) 1 + 2 IgG, SERUM (CLIA) : Negative
- TPHA; TREPONEMA PALLIDUM HEMAGGLUTINATION,SERUM @ (Agglutination) : Negative

I am developing a stye on my eye and have a headache and pain in my other eye. I have not showed any other symptoms other than these.

Should I be worried ?
- Are the above tests conclusive ?
- Till when should I keep getting tested ?
- Today makes it exactly 5.5 months after the encounter. Should I get re-tested again ? If I get a negative again, should I stop bothering and move on ? or should I get re-tested after 8-9 months ?
