thanks for your reply asaf.
i would like to add one comment which i just read on one of the post for Dr Sean Cummings which says the following:

A fourth generation HIV DUO test including antibody and p24 antigen will give you greater than 99.89% certainty at 4 weeks - and I believe these are available in Australia.

Lymph nodes swelling is not a very uncommon thing to happen.There are over 100 different reasons why lymph nodes can swell.I had a swollen lymph node for 3 months because of my teeth and i had 10 HIV tests done in a period of 1 year all done 6 months or more post an unprotected anal exposure with a girl of unknown status and all came out negative and mind you i went to different clinics using antibody tests , duo tests and even pcr dna tests.So swollen lymph nodes are no specific symptom.
I would advise you to , calm down and at 3 months post exposure get a standard antibody test , or get a PCR DNA test at this time right now will provide you with a very conclusive result and my advice is that next time engage in safer sex.

Vance isnt it true that when P24 anti is present it will be showed, and the moment it doesnt show that is because antibodies are formed and they will be detected. right?

Antibody test is the only conclusive test. Any negative is good but should have antibody test at 3 months.
