Dear Dr,
I am a male from Lebanon , Before 3 weeks i had a unprotected vaginal sex with a married woman that i dont know her hiv status. After at 16 days i made a 4th generation test and was negative , and for now it is 21 days and i dont have fever neither swollen gland or rash symptoms , my question is should i be worried or this test can give me a good sign ? And i have to confirm by another test at 6 weeks . The problem is i cannot sleep and i live in a big anxiety and my ibs is getting worse.
