HIV anxiety please help

after a possible exposure. To be exact this was my first time ever being with anyone at all!!! and still has been. Ive only had sex once in my entire life. i tested negative up to 3 months. after 12 weeks the person i was with tested negative. Also after 3 months i donated plasma and whole blood and both were accepted. at 4 months i tested negative for HiV again , and my recent test at 5 months came back negative. IM STILL SCARED!!! that maybe im one of those cases and in the furute i become really sick!! im beyond nervous and scared

dont worry you are fine

why would you think that ? you just said you and your partner both been tested negative. I don’t see any problem here unless you’ve had another exposure with someone else after five your last test. Just take a deep breath, forget about HIV and move on with your life, you have nothing to worry about.
