You have been exposed to risk of said diseases almost 6months back. You have a reason to smile because both the diseases have an incubation period
of one to two weeks only.
But your worries can end there certainly.....
You must be considerate and make a resolution for future not to enter in such risky exposures.
You may be an asymptomatic carrier of the infections and may have subclinical cervicitis
and could infect your present partener. He may remain asymtomatic for undefined period but may get symptoms anytime.
You also have risk of having HIV, Syphilis
whose incubation periods are about one to two months and patients may remain deceptively well for quite sometime and continue to infect others.
Please have work up for them all.
Hope you remain uninfected and safe,
all the best!
