Confused

Hello. I am a female mid 20s. About three months ago had a sexual encounter. Used protection for vaginal sex but did not use anything for receiving and giving oral sex. About two weeks post exposure I tested negative for Ghonorea (Gonorrhea), Chlymdia, Syphillis (syphilis), Trich, and HIV. However here is my dilema. I have a discharge with no odor now since that encounter . It is milky and white, and smooth. Would also like to note I retested for HIV and Syphillis (syphilis) at ten weeks and negative. For the discharge I was given metro gel and teraconzole both did not work and the discharge is annoying. Does anyone know if this is an STD? And if not what it is. I would also like to add that I have not been exposed since then. Thanks.

syphilis testing isn't accurate until 6 weeks post encounter.

you weren't at risk for hiv from this encounter.  

so you were seen and diagnosed as having bv several times now?
