The HIV tests we use in BC Canada have a window period of 3 months and are 95% accurate by 6 weeks. I have not heard of anyone seroconvert after one year.
There are no symptoms that are caused by just having HIV. The symptoms that someone gets when they have HIV are common to many different medical conditions. The only way to find out if you have HIV is to go for a HIV test.
We also don’t see HIV being passed when someone receives oral sex. There are some STI that can be passed when receiving oral sex but HIV is not one of them. Have a look at our “Know your chances” web page, it provides information on what STI can pass with oral sex.
It is normal for us to see people who are still worried about HIV and other STI after the window period has passed and their STI/HIV test is negative. Sometimes strong feelings like guilt and shame can cause people to be worried about STI. If you are having these worries It can sometimes be helpful to talk with a health care professional about your individual situation. Also have a look at our worry page for more information.
I don’t know your full situation but it doesn’t sound like you have HIV given that you had a negative test at 9 and a half months and we don’t see HIV passing when receiving oral sex. I would just recommend following up with your doctor if your symptoms do not get better.
