NSU possible infection

I may have been exposed to unprotected sex around 6 weeks ago. reason i say may is because i probably was but i was stupidly very very drunk. i panicked and went for chlamidya and gon test 6 days after, urine sample testing. came back negative. since then i had experienced what from reading is urethris 4 weeks after, and may have spotted discharge twice in this period which was completley clear (both times just before urination) so not sure if dribble before hand or not. in the meantime i was masturbating heavily between exposure and urethris i put it down to anxiety. i stopped masturbating 9 days into urethris and my symptoms have all but stopped and gone away, no pain in penis and slight discomfort after urination has gone. i have since tested negative for a UTI. my questions are has anyone tested positive early for chlamydia i.e in "window period" and if urethris was caused by infection would it usually just go away (coinsiding with no masturbation?)?

If you live in the UK my advice would be to go to a GUM Clinic at your Local General Hospital …
