Hiv scare please help
About a year ago I had two at home tests that turned out positive. Went straight to the clinic and got a natc test blood. And it was negative. I stopped having intercourse with anyone cause I was so scared. I stayed to myself. Fast forward a year, I donated plasma countless times about 10 times within a year , cause I was broke I was already cleared of the scare, and they do check all these things at the donation center. I donated for 8 months, I would assume if I did have hiv they would have told me very quickly. So I stopped worrying that it's been 8 months. I took another at home test that came out that I'm assuming is positive. But looks very negative because it's just a veryy tiny dash of a red mark at the end no full line. Really had to sit down and think if I did anything? And I can't come up with one thing that would have got me in the position to contract it? I do have an occasional partner I believe has also not done anything but idk I went and took another hiv at home test and the test showed negative but a very tiny speck of red showed at the end as its line was forming but didn't. Anyways I believe the test reacted to hiv again. I am trying not to get scared cause I've had this happen before, but I'm scared I don't understand why my at home test keeps coming out positive. The blood donation place hasn't deferred me so I figure my health is ok. Idk what to do to be honest, I don't want to donate anymore, cause my stupid at home test. I'm not sure if it's reacting to something else or these whole 8 months i had it idk. I'm only scared because from what I've I've read the test if any reaction on the t line, it's because it reacted to antibodies. Last time my test came out positive twice on the oraquick I almost lost it, but I don't understand why oraquick is giving me positive results all the time.
