So on December 28 2020, I hooked up with an old high school love interest and had protected vaginal sex. I was tested for all std two weeks prior (December 14) all came back negative, and since she is a trauma nurse she had to get tested for infections blood diseases a month prior (November) which came back negative. Me being nervous I asked her to get another hiv test, which she did willingly. She took the test February 5 2021, and it came back negative, I saw the results. I recently took a duo test but haven’t gotten the results back. Should I be nervous? Is there a chance my test can come back positive?
