Detailed Answer:
Hello,
Thanks for trusting Healthcaremagic!
I have gone through your query and I can understand your concerns.
The window period for the PCR DNA test is 2-3 weeks of exposure. In your case you have crossed the window period already, so the test is conclusive. You can go for a confirmatory test after three months for reassurance. International guidelines state that an HIV test is considered definite and conclusive when taken 3 months after an exposure.
In short, the chances for infection is very minimal in your case.
Wishing you good health
