hi, doc,
I am 28,male. I had protected sex with a female sex worker (oral and intercourse, less than 10 minutes).
I took Elisa tests at 5/6 and 7 weeks, all came back neg.
Do I have to wait to 12 weeks to repeat testing?
BTW,No obvious symptoms were found.
Thank you.

You didn't have a risk of contracting HIV and didn't need testing.

Thanks, but i still worry about the condom, is there any possibility that a broken condom I can not feel?

[Teak]

Nope.. Had it failed you would have known without a doubt.

Thank you for your comments and suggestions!
If it is an unprotected sex,  what is the window periods? 12 weeks? How about the accuracy of a Elisa result in 6 weeks?

Have anybody ever see someone turn positive after a 6 week negative?

3 months negative test will give you a conclusive results.
