How long does it take for a scan to show that one is pregnant?

A pregnancy can typically be detected via a transvaginal ultrasound as early as 5 weeks after the last menstrual period, which is about a week after a missed period. A standard abdominal ultrasound may show a pregnancy around 6 to 7 weeks. However, blood tests can detect pregnancy hormones as early as 6 to 8 days after conception. It's best to consult a healthcare provider for accurate testing and timing.
