Hi . It is clear that you are very concerned about potential exposure to HIV. I need to note that we are not medical professionals and, for your protection, cannot provide medical advice. I do want to share with you this article from our editorial team on transmission risks: https://h-i-v.net/transmission-risks. You will note that the risk from insertive oral sex is less than 0.04 percent. Of course, these are estimates and individual circumstances can change the risk. It is understandable that the symptoms you are experiencing are concerning, but there are other potential symptoms you did not mention (see here for early symptoms: https://h-i-v.net/symptoms/early-stage) and there are multiple potential causes. The only way to be sure is through HIV testing. This article discusses the various types of tests, including information on the window for when the tests are viable. Hope this information is helpful.
