now I should wait 4 weeks
If a condom fails it is a large rip down the seam and it hangs in tatters so both of you would know if that happened. Micro tears are a myth.
You can't get HIV since you used the condom, so you are so safe that there was no reason to test. Time to move on from HIV.
You don't have any medical training so it is doubtful if you would know what swollen lymph is like. Often when people are scared, they have symptoms in their imagination so try to relax and see if they go away.
So dr what do u thin ? Is there any possibility to chang the result from negative to positive after 8weeks ? or not ?
