It would be good to go for a follow up STI test. The tests you get depend on what happened at the clinic.
Gonorrhea and chlamydia are two STI that can cause burning when you pee. Most gonorrhea tests would show a positive result by 7 days. Most chlamydia would show up in a test by 2 weeks but sometimes this can take as long as 6 weeks.
Sometimes if you go to the clinic with symptoms of an STI they will give you treatment to cover gonorrhea and chlamydia. If this happened to you there is no need for further testing for these, just wait a week for the antibiotics to work. If they did not give you antibiotics I would recommend going back and repeating the test at 6 weeks.
With the blood tests e.g. syphilis, HIV etc… we find that most of these results are accurate by 6 weeks but can take up to 3 months for a final result. You could repeat the blood test at 6 weeks or wait and get them done at 3 months. Really depends on your individual situation.
In regard to when it would be safe to have sex again it really depends on what your initial test results at the clinic show and how your symptoms are going. I would recommend talking with the clinic that did the testing for you.
As most STI do not show symptoms it can be hard to know if you are putting someone else at risk until you get your final results from your STI testing. This can take up to 3 months for most blood tests. While waiting for these test results I would just recommend having sex in a way that would reduce your chance of passing something on. Have a look at our “Know your chances” web page, it provides information on your chances of getting or passing an STI depending on how you are having sex.
In regard to HIV risk, HIV is not commonly passed with the sex you described.
