I had unprotected vaginal intercourse with a woman of unknown hiv status on the 8th October 2020 and immediately started PEP within 24 hours of the incident.I asked her and she said she has nothing.But i have been soo badly stressed ever since the incident.so after 20 days I was prescribed a tridot hiv test.It came out non reactive.Even hepatitis B surface antigen test came non reactive,and hepatitis C virus antibody test came non reactive.so am i safe or do i need more testing.Is there a chance that my negative report will turn positive in the coming days.now i am imagining lymph nodes also.iam very anxious.please help.i can't sleep at night.
