I had received unprotected oral sex from a girl which i don't know on 26 dec 2016 followed by protected vaginal sex. After that following week i actually drink too much of vodka and passed out in night and later on had a deep tissue thai massgae. Next week i feel very week and little feverish. Then i read too much about hiv on the internet and i feel like i contracted hiv. Then on 29 Jan 2017 i got tested for hiv screening test (they took blood sample from my arm ) which was non reactive. Doctor told me its negative. Then i again got anxious after a week. I tested again from two different laboratory ( blood sample taken from my arm) on 13 Feb 2017 and both result were negative. So i want to ask that should i have to test again now or not. I didn't had sex after 26 Dec 2016 and i am feeling guilty all the time. Now i am even afraid of kissing some girl. Its always in mind that if i got any disease from them. Please help me out of this i am really in big tension.
