Thanks for providing more information.
With any history of unprotected sex,risk for STD is present.
All STDs can be tested by 6 weeks of exposure, but precautionary tests can be preformed as early as few days after exposure.
However the timing for the tests depends on the type of STDs.
For Gonorrhea, Chlamydia, Trichomoniasis etc, the tests can be performed from 2 days to 2 weeks.
Herpes can be tested after 1 week of exposure and repeated again after 6 weeks.
HIV can be tested at 6 weeks and 3 months.
With one time unprotected sex,chances of HIV is 1 in 1000.
In most of the STDs,symptoms like Bumps or blisters on genitals,burning or pain during urination, Flu-like symptoms, including fever, chills, and aches,swelling and pain in genital area , unusual discharge present.
However sometimes STD like HPV shows no early symptoms as well.
If you don't develop any symptoms in next few weeks then chances of STD are less.
I suggest you to visit GUM clinic for STD profile for further evaluation and management.
I hope this helps.
