I have a pregnancy test, need further clarification ?

Decide on the result: Decide whether the result is positive or negative. A test gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a regular period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant.
