last 2017, i Have done one thing i regret is doing a unprotected oral sex to the csw (im the one giving). 4 to 5 days later due to anxiety i went to a hub for swab/gram stain test in my oral and penile if i contract a gonorrhea. the test came out negative. until today i still saw some whitish phelgm in my throat and i have sore throat (but so mild that i dont feel any pain at all). is my test reliable? or should i be afraid for DGI?
