Is it possible for a blood result to come out negative after couple days of unprotected sex? my boyfriend came in me as well

Yes: If you had intercourse at the most fertile period, it could take up to 12-14 days for the pregnancy hormone HCG to show up in the blood. It is possible to be pregnant in this time window.
