A member asked:

Is a pregnancy test result 23 days after sex reliable ? took it and it said negative.

A doctor has provided 1 answer

Preg. test negative?: Urine pregnancy tests depend on implantation of a fertilized egg, so "23 days" after unprotected sex depends on when the test is taken. To be certain obtain a serum test (HCG) from your healthcare provider if your period is delayed from normal. It is very accurate, and urine :over the counter": tests are not always reliable.
