HIV test for different strains

[needinfo1981]

I am still worried about a encounter I had with a CSW 11 months, she gave me protected oral and I fingered her. For the past 2 months I have been having abdominal pain and I feel like my bowl movement has increased from 1 to 4 times a day, for which gastrologist is telling me I have GERD (gastroesophageal reflux disease)and also I am having rashes for which dermatologist has told me I have excema. Are problems coincidence or HIV symptons.
I am really worried about HIV.
I have had several HIV tests
8.5 month HIV1 Home access kit antibodies - negative
9.5 months HIV1/0/2 antibodies - negative and all the other STD test all came negative
10 month HIV1 Home access kit antibodies - negative
11 months HIV1/0/2 antibodies - negative
11 month HIV DNA by PCR - negative

I understand all the above test results which came negative are good sign but can I completely rule out HIV or is there any chance of some HIV strain/subtypes not detected in the above tests?

You never had an exposure and didn't need testing for HIV.

Believe your results. Further testing would be a waste of time and money.

you've done all that testing and you NEVER had a risk !

accept your negative status...you dont have hiv
