I live in a country where HIV prevalence is very low about 0.03%. However the numbers are on the rise. My exact question is I had a risky exposure on March 24th. Condom broke with a CSW. I had three tests up to now. On 18th day from the exposure ARHITECT COMBO test, p24 antigen test; on 29th day ARHITECT COMBO test again and finally on 33rd day same test. All came negative. But now I'm worried thinking whether the needle that used to draw blood might have had HIV on it and I'm infected. I know the thoughts are irrational and I'm fine. Although that being said I'm crippled with anxiety because of these continuous thoughts. Kindly share your thoughts.
