No. Testing at 13 days post-exposure is too soon to rule out HIV. If the result is positive, it is definitive. For a definitive negative result you need to get the test a 6 months after exposure. You may repeat the test between now and 6 months and it stays negative, do get it at 6 months. Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines
