How early can you find out your pregnant?

Pregnancy can be detected as early as 10 to 14 days after conception, which is about 4 to 5 days before the expected period. Home pregnancy tests can typically detect pregnancy 12 to 14 days after ovulation. However, blood tests performed in a lab setting can detect pregnancy as early as 8 to 10 days after ovulation. These tests measure the level of human chorionic gonadotropin (hCG) in the blood, a hormone produced by the developing placenta.
