Some stuff won't show as there's 'incubation period'. Get tested now and test again in 4-6 weeks to be sure. If you have a partner and usually have unprotected sex with her, avoid it for a while until you get your 2nd test results. If you cannot, invent an excuse to use condom with your partner - This happened before with me and I lied saying that I felt burning while pee and may have a urinary infection so better to use condom for a while...
I've heard many stories of wives/girlfriends becoming aware of husbands/boyfriends secret habits once they are diagnosed with STD during routine check.
