Negative HIV test. Can I trust the results?

I did several home tests for HIV , I have negative results, yet I need some clarification. I think I did the tests wrong. Please, I need some advise. I ordered 3 different testing kits (one oral swap and two blood-based tests). All three came out NEGATIVE (one line). Yet since the documentation was in Chinese (I can t read it), I am not sure if i followed the procedures correctly and now I am freaking out. Both blood tests same scenario: I dropped one drop of blood and one drop of the other liquid - no reaction for 5-6 minutes. Then I dropped both times another drop of blood and another drop of the liquid until I could see that the stripe started developing. Both came out negative after a few more minutes. The oral test: I did the mistake to touch the swap with my hands, even tried to remove it, since it seemed too big in order to get into the container. After I realized that i didn t have to remove it, i performed the test and got again a negative result (one line). My question now is, due to my stupidity: What are the odds that I did something wrong? Can I trust those results or not? PS: I take those tests 8 weeks after my last protected sexual encounter, yet oral was unprotected (hetero).
