We find that it is possible for gonorrhea and chlamydia to pass when a woman is receiving oral sex, but it is not a common way for these two STI to pass to someone. Your partner would also need to have these STI in the throat for there to be any chance in the first place.
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.
As most STI do not show symptoms I would recommend going for a test if you are concerned. Most gonorrhea and chlamydia would show up on a test after 2 weeks. Have a look at our “STIs at a glance” chart, it provides information on how long you need to wait before getting tested (window period).
