The very earliest a home pregnancy test can detect a pregnancy,

is 6 DPO, or 6 days past ovulation. However, some babies will not

implant until as late as 10-12 DPO, which in that case, a pregnancy

test would not be able to detect a pregnancy until after the period

is missed. For a pregnancy test to be able to detect a pregnancy,

the baby has to have implanted into the uterine wall, so that hCG

can be produced. HCG can be detected in the blood before it can be

detected in the urine, so if you really want to know if you are

pregnant, you might want to get a blood test done by your OB.
