The earliest a pregnancy test can be positive is typically about 10 days after ovulation, which is roughly 4-5 days before a missed period for most women. This early detection is possible with high-sensitivity home pregnancy tests that measure the levels of hCG (human chorionic gonadotropin) in your urine. However, for the most accurate results, it's recommended to take a pregnancy test after missing your period, as hCG levels vary among individuals, and testing too early can lead to a false negative.
