In brief: Very low
It depends on how "early" you are referring to, but generally, the blood test for pregnancy is very accurate with a very low false negative rate.

In brief: Can be false 17 days
A serum pregnancy test can be falsely negative up to 17 days after intercourse.
Because urine pregnancy tests are less sensitive, it could take up to 3 weeks before turning positive after insemination.
