Can I have HIV even after protected sex?

Hi doctor,

Before nine months, I had sex with a girl and this was my first exposure. I had protected sex by using condoms. I had incomplete sex as I did not release any fluid outside. But there was a precum on my penis in low quantity. After sex, I tried to remove my condom and my partner stopped me and she started to remove the condom. After removing it, I pulled the upper skin of my penis with the same hand to cover it. I am not sure whether I touched the inner skin or not. But I am worried about the precum on my penis. It does not have any cuts or sores or any other kind of infection. After this, she cleaned it with a cloth and I dressed myself. My life was running well. After a few days, I started to think about the situation seriously and I am worried about HIV. On the same day, I started to have symptoms like diarrhea and dry throat. I was not able to eat anything and I did not feel hungry and I was not able to sleep properly. I had these symptoms for a week. Am I infected with HIV? Please help me. I got tested for HIV 1 and HIV 2 antibodies after three months of sex. The result came negative. I am scared about HIV because of my smoking habit. Will it produce a wrong result? After three months, I had a fever, throat pain, illness, and diarrhea. I tested positive for COVID-19. I started taking medicine and these symptoms went away. I did not test for COVID-19 again as my symptoms were gone. But now I had a mild fever for two times after COVID-19 symptoms are gone. Should I need to test again for HIV?

Thank you doctor,

Do the test is accurate and sufficient for conformation? Does smoking produce a false negative result? Even after COVID-19 symptoms are gone, why am I having a fever for a short time? Please clarify my doubts.
