When Can You Test for Pregnancy? Understanding Early Detection

Pregnancy tests typically detect human chorionic gonadotropin (hCG) in the urine or blood. hCG is a hormone produced by the developing placenta shortly after an embryo implants in the uterus. Home pregnancy tests can usually detect hCG in the urine about 10-14 days after ovulation. This would be about 4-5 days before the next expected period.

Blood tests for pregnancy can detect hCG even earlier - sometimes as early as 6-8 days after ovulation. These tests are performed in healthcare provider's offices and are highly accurate in detecting pregnancy, even before a period is missed.
