First off, I wanted to disclose that I do have a history of anxiety and I recognize that this may be contributing to my fears. I am a female in a heterosexual monogamous relationship. Prior to becoming intimate, my partner and I got tested for most STI's including herpes 1 and 2 as well as HIV 1 and 2. All came out negative. Prior to our relationship, my partner confided in not having had intercourse with anyone for about 65 days prior to us meeting and is big on having used protection in the past. We use protection most of the time due in the relationship as a contraceptive method, however there have been a few times where it was not used. One particular time using protection, the condom slipped off during sex after he had finished and some semen did spill out while it was still stuck inside. Due to my anxiety, I convinced my partner to test again (this will have been 1 month after initially going together to get tested) for HIV using a rapid 4th gen antibody test and it came back negative. I don't have any reason to believe that he has been unfaithful during the relationship, but I have always been raised on the notion that condoms should always be used even within a monogamous relationship and feel wary that (even if it's a small unrealistic chance) I may have put myself at risk. I have been looking into testing guidelines and most still state that regardless of what generation of testing is used, that you should still go back at 3 months for a confirmatory negative result. I find this stressful as I would just like to test exactly at 28 days with the DUO and put this worry behind me. I know that window periods have been changing over the last several years due to more accurate diagnostic tests, but just want a confirmation that with a negative result at 28 days post possible exposure and can move on with my life and relationship and COMPLETELY put this worry behind me, without a need to go for any follow up testing related to this exposure. For complete assurance, I also plan to order a DNA PCR HIV test on the same day. Would a negative result from both, or even one, of these tests be enough for me to move on? Thanks.
