Hi there, Protected anal sex is extremely low risk - no risk at all, unless of course the condom was used incorrectly or broken etc. Unprotected oral sex is also a low risk exposure but there is a risk of transmission nevertheless. It is said that around 1 in 1000 oral sex exposures will lead to HIV infection if one or more of the partners are HIV positive. I would recommend to test following your exposure with someone of an unknown status however, it may be too early to test using our test. You are welcome to use our test whenever during the 12 week window period but a negative result is not conclusive until 84 days post exposure. I would recommend that if you are very worried to get a test done at a clinic (but please be aware that many GUM clinics are closed due to COVID19). The symptoms you are experiencing may be related to HIV but there really is no way of knowing unless you test. I hope this helps, and I hope that you are able to test and know your status. If you have any other questions, please feel free to leave them below. Kindest regards, Becky
