I am glad you reached out because I can tell from your writing you are dealing with so much worry and it can really impact your stress, like you said, getting headaches. HIV can be transmitted through five bodily fluids including breast milk, blood, precum, semen, and vaginal secretions. It cannot be transmitted through saliva, and in the case of transmission through oral sex, the risk is at the lower end of the spectrum compared to unprotected vaginal or anal sex. You can definitely learn more about the specifics which may ease your mind through this article: https://h-i-v.net/transmission .
That being said, the Centers for Disease Control and Prevention in the United States actually encourages everyone between the ages of 13 and 64 to have at least one HIV test (more here: https://h-i-v.net/diagnosis-testing), so if you've never been tested it might be a good thing to add to your typical medical care. I have heard from others that testing is less overwhelming and that the testing personnel is more supportive than they thought they might be.
I hope this is helpful to you! Keep us posted and we wish you the best.
