Yes, most pregnancy : Tests depend on the detection of a certain level of HCG in the blood. It takes about a week after fertilization (sex that results in pregnancy) for any pregnancy test to be positive (even the blood test). After that time, the blood test will reliably detect pregnancy, and after 2-4 days the urine dipstick test will reliably detect pregnancy.
