Syphilis testing at 6 months

Hello I had an  unprotected vag sex at the end of July 2017. My doctor was  persistent on me taking a 6 month HIV and Syphilis blood test (RPR) below are the tests I have already taken.
Aug14th neg RPR
Dec 6th neg RPR
Feb 8th is still pending
I received my results for HIV NEG.... so now my question is. Is there a chance my neg 4month RPR will change? I thought the window period for Syphlis was 3 months. I am really nervous and this is my final test and I can move on. Please give me information. Thanks for all you do here.

Window period for HIV depends on the kind of test you go for.
-If is a combo duo ag/ab it will be accurate 28 days after the encounter.
-If is a normal antibody test (finge-prick) it will be accurate 3 months after the exposure.

Regarding syphilis, 6 weeks is a good time to wait before testing. But if you get it negative, is good to re-test 3 months after the sexual exposure, as there are people that take longer to show a positive result.

All the best.
