Need expert advice. after sex, how long should you wait until you get a syphilis test to make sure the virus has already shown up?

Early syphilis: Initial syphilis manifests on the average of 21 days as a painless ulcer in mucosa/genital areas... If this lesion was missed becuase the ulcer is normally painless I would get the test in 2 months. That being said, i would also get a test for other sexually transmitted diseases like hepatitis C and B and HIV. Syphilis is a spirochete -- a type of spiral-shaped bacteria and not a virus.
