I had unprotected sex 10 weeks ago with a man I had been in a relationship with for a few months, in which he ejacualted inside of me. 2 weeks later I had sex with a man I had casually been dating for a few weeks. At that time he entered me without a condom for maybe a minute before I made him put on a condom. I have been very nervous that these irresponsible activites have put me at risk for HIV. When I was with these men they both indicated to be clean of any sexually transmitted diseases. However due to my anxiety I had the OraQuick oral swab test yesterday which came back negative. I am still nervous and do not feel convinced that I can assume that these results are defenitive. Please advise
