Q: When is the earliest that pregnancy can be detected? Do I wait to miss a period for confirmation?

A:Urine is tested for beta HCG (human Chorionic Gonadotrophin) - by pregnancy tests and most of these kits available as OTC products for home use. These may be able to detect pregnancy as early as 7-10 days after conception. However, to be absolutely certain the test should be repeated a couple of days after the first missed periods.
