Brief Answer:
12weeks

Detailed Answer:
Hi

Thanks for asking.

HIV testing by the ELISA test can give false negative results upto 12 weeks of the exposure due to the window period effect.

As your exposure was on 18 XXXXXXX a completely safe time to get the test done will be 12 weeks after 18 XXXXXXX i.e 18 september.

I think you should redo the test at that time, as a negative test will be sure enough to rulwe out HIV.

Also get yourself checked for hepatis B, Hepatis C , Chlamydia, Gonorrhea also as these STD are also very common along with HIV.

Thanks.

Please let me know if you need more information.
