ELISA test values changing

Hi,
I had a protected(double condoms) sex with a prostitute,after 20 days i got shingles ,after 20 days of encounter i tested for hiv ELISA method and the test value was 0.02 non reactive,and the refrence range was like this
>0.9 non reactive
0.9-.1 intermediate
<1 reactive

again i got flu and cold which lasted for 15 days,swollen nodes and throat pain,disturbed stomach, i again tested after 55 days,i tested non reactive with a value of 0.22,
after about 150 days(5 months) i tested again,the result was non reactive with a value of 0.31.
i m worried about the increasing values of the test,why does it increase.does it mean it will keep increasing upto  the last value of 1.0
kindly help me,i am very tense about it.

Dude you are conclusively negative.. Never double bag, it increases the risk for condom tear.

Thanks bro.

but i am worried,why these values keep increasing. i am afraid,it would increase upto the reactive range.
i just want to know why it increases?

you no need to retest... 5months is more than enough... 3 months is conclusive... forget the numbers....
